Duelund conversion to DIY Helix Geometry Cabling


I have been an avid user of the Duelund cabling for over two years now and have used them exclusively in my system with great results. I have built many for friends and have used a full loom of interconnects, speaker cables, power cords and an extensive wiring modification for a previously owned balanced power conditioner utilizing Duelund 600V PolyCast wiring which was transformative. My cabling desires can be a little addictive as I have owned and evaluated 40+ brands of cabling costing more than an entire stereo system!

Over the past six months I stumbled upon a thread here on Audiogon in regards to a Helix designed cabling and as you probably already know, I just had to look a little deeper into this cable design…After a month of studying and sourcing parts, I decided to reach out to the designer/architect, Williewonka who gave more insights and philosophy on how the cable came into existence.

That conversation got the ball rolling in converting one of my KLE Duelund interconnects to Steve’s Helix designed which only entailed replacing the neutral with a Mil-Spec 16 AWG silver-plated copper wire with the neural wire being 3 times longer than the signal wire and of course the “Coiling” of the neutral wire : )

After the modification was complete, I was not sure what to expect from the Helix cabling but I was quite shocked with the results with “ZERO” burn-in time…The sound stage became much wider/deeper with a much tighter/focused image and clarity/transparency is like nothing I have ever heard in any cabling regardless of cost. In fact, I just sold a full loom of a commercially designed Helix Cable that’s renowned around the world and has more direct sale than any cable manufacturer; these $200 DIY Helix Cables walked all over them…

I believe you will hear the same results as I have and have heard back from friends who have already modified their Duelunds with the same results; WOW! Remember the cables will need 200+ hours to burn-in and settle into your system. My system is now 90% DIY Helix to include IC, SC, PC and Coax with each cabling adding its beauty of an organic and natural presentation that draws you into the fabric of the music.

You can tailor the sound of your cables using Duelund, Mundorf silver/1% gold, the outstanding Vh Audio OCC Solid Copper or Silver with Airlok Insulation or your favorite wiring and you can change it at any time…

I have started to Purchase the Wire to produce my first Cables.
I have the 0.9mm PC Triple C Solid Core as part of this order.
It will seem that I am deviating a little from the recommended wire in the cable build posts, but the spirit of investigation is intact.

I also now own regular build PC Triple C IC's that are to be delivered,
along with already mentioned regular build D.U.C.C IC's 

I have also purchased a IEC and UK Mains Plug that can take Crimped Spade Terminations used on the Wire.
My Nanotec Strada 308 PC Triple C Cable can now be compared to two other Power Cables and the Helix Power Cable when it is produced.

I have an inquiry, does anybody know how long a cable is submerged into a Cryogenic Tank and how the process is carried out to return it to a normal temperature ?

I live in a area where there are few Horse Breeding Studs and AI is a common used method for impregnation, hence Cryogenic Tank usage might be able to be achieved.  

Thanks Steve

                      The info helps a lot, as I am encouraging others to consider this design for their future cable projects, I am on boards as well, and have nearly all the materials to start.

The Power Amps are still to undergo conversion to Balanced, hence my slow to start performance.  

This Thread has got my attention, the very good reports on the use of the cable design is very appealing.
It fits quite nicely in with a plan I have been pondering, and to mirror other areas of my HiFi, as I  have a System mainly using Devices that are Bespoke Produced.

The idea exchanging my Branded PC OCC Copper and Silver IC's,
to produce a Cable Interface with Bespoke Produced Cables has been on my mind for a period of time.

I have recently been investigated the latest Wire Production Methods being used and that are available from the reputable wire producers and have had become interested in Mitsubishi D.U.C.C
and Furukawa PC Triple C.

I have purchased a D.U.C.C IC and a Nanotec Power Strada 308
PC Triple C Power Chord.
Either of these is yet to be trialled. 
The Strada 38 has been supplied with Spade Termination but with out Plugs, If a Suitable UK Spec Plug for this cable could be recommended,
that will help get the trials moving.   

I have discovered during my research a Supplier of PC Triple C wire.
Before I attempt to use a buying service for the Cable.
I am keen to know if the available Wire is usable for IC's and
Power Chord, as the ( AWG ) differs from the commonly referenced
( 16 - 18 AWG )

The listings from the supplier show the Wire can be ordered as :
7 x 0.18mm ( 33 AWG ) PC Triple C
25 x 0.16mm ( 34 AWG ) PC Triple C

7 x 0.3mm ( 28 AWG ) PC Triple C / EX - 5N Silver Outer Wall -
Conductivity 105.0 IACS.

Any advice that can be offered on using the above Spec of cable will be very much appreciated.

 
  

I have quite a stock of PC Triple C Wire to produce my Helix Cables.

I am behind with this as a task in hand as with many other tasks to be completed.

The Dual Mono Balanced Pre is still to start, as well as the conversion of the Power Amp's to Balanced, so it is not too much of a pressure at present to achieve the Cable Build. 

I have been talking about my impressions with PC Triple C and loaning my assembled Interconnect Cables produced with this wire to other HiFi enthusiast friends, many of whom are sure that the OCC wire already in use, is not going to be improved upon.

There are, as a result of my interventions and passed on word of mouth reports,  new reports becoming regularly seen on the usage of the wire, which is slowly bringing to fruition a host of individuals starting to replace their OCC wire with the PC Triple C wire Interconnects. 

It would be great if a respected authority on the Helix Design could adopt the PC Triple C wire and produce a build with this different wire design.

Not too long ago, I would have claimed to have had a gut feeling that something that could impress was achievable, as that was my own singular experience, with the recent activity, I am feeling very confident there will be something on offer that has not been experienced, and will create a positive response.     

@williewonka The Speaker Cables being adopted by the other converts are Solid Core SAEC which I have learned has an increased gauge to my supply, which has a 0.9mm (19 awg) diameter Solid Core wire. 

I will PM later with a link attached for the Wire I use, that is easy to obtain, a couple of the stranded wire types has proven difficult to acquire.

If this wire is off interest, it will be worthwhile looking at D.U.C.C, as I am using this wire and CCC as standard assembly RCA Interconnects, the D.U.C.C offers a slight perception of adding a hint of richness when compared to PC Triple C, but has proved to be more more attractive that OCC interconnects, especially for the differences noticed to quietness and smearing.

I found D.U.C.C really stood out when used on my digital source.  

@williewonka The Link is to the Solid 0.9mm PC CCC Wire I have acquired. 

The price is per metre in length, so this supplies two single wires at a common Interconnect Length.

This is the wire that has superseded my Mapleshade Clearview Double Helix that was used in my system for many years, and also a Speaker Cable that held its own at a Speaker Cable Bake Off where much more expensive cables were in the line up.

There is also a slightly thicker Solid Wire available from Acoustic Revive Speaker Cables.     

https://www.fromjapan.co.jp/en/special/order/confirm/audio9:10004950/2_1/lgk-link_top_search

The D.U.C.C Wire is produced by Mitsubishi and it is Mitsubishi Cables that I have that are terminated with Aeco Silver RCA Plugs.

The D.U.C.C Wire can be found used by Acrolink in various Cable Types, Audio Technica use it in a various Cable Types and as a blend of a wire with other wire types, Luxman produce a dedicated Phono Cable from the wire.

Mitsubishi produce a Speaker Cable that has a Solid Core Wire. This is the Wire I am looking to acquire to produce my own Cables, it is not as easily discovered for sale in a long length, as the PC Triple C is.

SAEC are the only Company I know using ePC Triple C in a Tonearm and this is selling for $13000.

After encouragement a friend who produced their own Tonearm Design has now used a PC Triple C Wire within the Tonearm, as a continuous Wire from the Cart',   I picked up on the deathly silence on my first demonstration a few weeks past and was of the comment that it was another incremental move for the betterment.

When the sheath is discovered that is extremely soft and supple, it will be a very worthwhile upgrade choice.      

  

I have meticulously read through about 70% of the Thread and have a much better grasp of the preferences of the Cable Builders.

My Last list of Cables was presented was more in keeping with selecting cables for a Version of IC's I had in mind.

This thread has caused me to rethink that earlier thought pattern.

I had continued a Search since my last post and discovered a supplier of
PC Triple C Wire 34 x 0.18mm ( 18 AWG ). 

As a result of the discovery of the wire supplier I was hoping to discover a positive report on using this AWG 'Stranded Wire' within this thread.

I believe Steve - 'williwonka' tried a version with stranded wire on a Guitar Lead ?

Also 'grannyring'  has reported on the using of stranded wire,
but has sung the praises of Solid Core and the much improved benefits of using it.

With this additional information as a motivation,
I have extended my search and come up with a option that is in keeping with the preferences being made on this thread, and I hope is seen as useful to the inquisitive Cable Builders visiting the thread.

Acoustic Revive are producing a Speaker Cable that has a 
PC Triple C Wire Solid Core 0.9mm ( 19 AWG ).
The cost of this is sold by the Metre ( 39 Inches ) @ GBP £ 6.00.
Effectively £ 3.00 per Single Metre Length.

It will be purchased to be Imported.
Shipping and Import Levies will apply to the above. 

Additionally I have in the past been working out RCA Plug Options for 
RCA's I as intending on experimenting with.

I bought Aeco RCA Connectors with a Solid Silver Live/Centre Pin.
( Similar to KLEI pricing )

I was also going to try out Zavfino 1877 RCA Connectors with a
OCC Copper Live/Centre Pin. ( Quite Affordable for Four Units )

I have not seen the above Connectors referred to during my reading of the thread.

A Friend has KLEI RCA Connectors in  both Silver and Copper so these were going to be used to assist with the assessments of the Cable Builds produced by myself.  
 
As a side:
I have indirectly entered the world of Helix Cables as I have in use for many years Mapleshade Clearview Double Helix Speaker Cables. 
These Superseded all other cables I owned.
  

@williewonka  Thank You for your assessment, and encouragement to continue with the PC Triple C Solid Wire.

It is satisfying to know that I have a Solid Wire, that will be quite useful for my Interconnects which are most likely to be XLR with Atlas Plugs.

If it is not myself to be first build a Helix Design Cable with this wire type, when eventually a build appears, it will become an alternative version and in keeping with the R&D carried out by others on some of the other Helix Versions already offering the positive user impression that caught my attention.

I will one day join the Club, and much of the footwork is done to get on board.  

@mbolek This is great news that you are taking on the Two XLR Builds with wires very well known and the lesser known off wire.

You will be a pioneer for the CCC Wire Version and I eagerly await your thoughts being made known about this build. 

When I finally chose to maintain the PC CCC Wire as a Speaker Cable over the Mapleshade Clearview Double Helix Cable, it took a little longer to convince myself to continue with the CCC wire than it did for the interconnects, the interconnects  was decided on quite promptly and after a period of time in use and then reintroducing the OCC, the CCC was reinstated with an immediacy.

Maybe the Solid Core CCC needs a little time of usage before it finds it voice.

Unfortunately, I can't rush into such a practice as the System is to be put in to storage for a period of time during 2022, due to an upcoming re-construction on the home demanding lots of funding. 

 

   

I eagerly await the report on the PC Triple C XLR Build that is imminently to be produced by @mbolek 

This is where my interest lies and it will be good to see the Pioneer Wire used for the Cable produced and put to service. 

I recently Purchased Plugs to connect to the PC Triple C Power Cables.
In the past week I have been using the Cable on a CDT , DAC and a Phonostage.
Each Device that has had the Power Cable attached had presented in a much more attractive manner.

The Room is being percieved as being more voluminous in the Soundstage Presented, as if a Ballon has been given quite a few extra pumps of inflation. 

Helix Cable Materials are not too far of being delivered.     
I will keep the Thread Posted on how I progress and the Wire Materials being used.
At present the intention is to produce a full PC TripleC 'IC' with OCC Copper RCA Connectors  
AWC-10 PC Triple C is the same Wire used in a Furutech Power Cable.
It is available as a Bulk Buy Wire, but the Ad's I am discovering have it reported as Out of Stock.
It is dufficult to determine if the Non Availability is permanent, as I have not got a direct communication with a supplier.

AWC -10 or AWC-11 PC Triple C are available as a Bulk Buy Wire.
These are on my Wire Order, but are a  20 AWG Wire. 

@mbolek You are en route and I am looking forward to reading your feedback about what you are perceiving.

@williewonka Your descriptions on the Cable Types and function is making a lot of sense.

Since I have dropped my barriers against Cables and their effects being a fantasy, I have made it my goal to find away to understand how a Cable construction can influence the sound.

After Capacitance and Methods to Screen out Interference, Lower S/N then the types of Wire used start to appear, and then configurations for the wire in use.

With a basic understanding of the above, I stumbled onto the Helix Thread and found myself inspired and most importantly willing to participate, which is now to the point, I have the Wires of choice to commence.

Whilst gathering information and making inquiries to more educated individuals about the importance of some of the electronic considerations for the selection of wires and a Cable Design.

I learnt of a few other things to consider, and that was the importance of the Connectors in use and whether the wire to be used for a Cable can commence its route within the device itself.

Making a decision about a wire within a device is reasonably easy if it is out of warranty and the circuitry design lends itself to the method to exchange.

This has already been agreed to be carried out on my Power Amp's when converted to Balanced and Single Ended, the New Pre Amp is to have my wire choices used from the off.

The connectors used for Single Ended Signal Paths, both connector types,    Chassis Mounted and Cable Attached are more of a challenge.

I have been informed by an individual who has used many Brands Connectors to produce cables, with  Connectors across a range of differing purchase prices to produce Cables or exchange Connectors on bought in Cables.

That there are variables in measurements regularly being discovered when testing  certain Brands and some of the most varied fluctuations are able to be seen on Brands that are sought after for their reported qualities.

The same person has informed me that the Chassis Mounted Connectors can have a very noticeable impact on the sound, and the ones that are Pure Copper with the minimum materials used to produce the part, has in their view the most impressive impact on the sound quality.  The attribute is described as not only being down to the material used but also the mass of the part, as there are less residual signal retained that can be detected as smearing when the signal completes the path.

With the above in mind, is there a possibility that a little more could be extracted, if a thought process was put in place, focusing on how to provide a device that has a thought gone into to it, that will enable it to work as an improved interface with the Cable Design.     

 

    

The MPT Pure Copper Male RCA Plugs and WBT - Nextgen - Chassis Mounted Female sockets are the connectors I will have on a shortlist for any future Single Ended Interfaces.

I already own Aeco Pure Silver Plugs, so I can do an A/B evaluation when the time arises.

When in discussions, the descriptions offered in favour of the MPT > WBT parts when used coupled together, are the ones claimed to be producing quite noticeable improvements, and enough to no longer use other highly regarded parts used for umbilical connections.

The investigation into the above pairing of connector parts, is an option for others who are interested in this design of Cable. 

As stated earlier, for some who do share the interest, the Chassis Mounted Socket might prove to be a little difficult to consider as a exchange part.

I am still working with the XLR options but at present, the Atlas Plug on the Cable is looking the most likely. 

The Chassis Mount options are very limited as well, when pure metals are the wanted materials.  

I have completed the Order for the Wire Types I have made known previously.
There is one small change to my Plan, as the Cables will ultimately end up as XLR.
This change has occurred as the Engineer who has produced my Valve Monoblock Power Amp's has agreed to turn the Amp's into a Balanced Design.
I made the inquiry as I am intending on having a Pre Amp Built that will also be in a Balanced Version of the popular DIY Model.

I will carry on with the Plan as discussed, if I choose to buy RCA Connectors and not repurpose owned ones, I will not invest as much into purchasing the RCA Connectors.

Is there any other things I should consider when allowing for the Wire Usage, to work as both single ended and at a later date balanced ?  
Another PC Triple C Doner Wire I have discovered for this design for a Power Chord is:
SAEC SPC 850 it is a Cable with 3.4 sq mm ( 12 - 10 AWG )
As a cable it has Two Stranded Wires per Metee Length.

In a very recent investigation, I have seen it sell for £ per metre and under, Shipping and Duty will be extra.

Any thoughts on this as a cable will be well received as I have a opportunity to purchace this and have sent with my other Wires,
that are in a Package that has a shipping deadline that is very close.
The Following is a report I have made on another Thread.
The Report is about Standard 5 Pin DIN to RCA IC’s, with Three Different Production Methods used for the Wires.
I will assume D.U.C.C is the Purist Copper, then PC Triple C and OCC.
I will assume that D.U.C.C have a crystal shape and alignmement that differs to OCC.

I am in a position to make a PC Triple C Double Helix IC, as the Wire materials are now with me.

The System used is a SS System.
It is familiar to me and I have had appriximately 20-30 Hours of listening to it Prior to COVID, I also got a few hours listening during 2020 when restrictions allowed for it, and when I loaned the D.U.C.C. IC’s
_________________________________________________________

On Friday of this week an opportunity was taken to visit a friend now we can visit to anothers Home in the UK.
COVID restrictions on Travel are eased and well received.

During this Visit the Resident HiFi was on the agenda, as well as Cables.
Three Cables were put to use as Tonearm Phono Cables.

OCC is the resident Cable Wire, D.U.C.C Wireand PC Triple C Wire were to be compared to OCC and each other.

OCC was first in use and it was delivering the performance to the ususal very high standard.

The exchange to D.U.C.C was immediately noticeable, there was a clearer insight to the presentation.
The Vocal became noticeably separated and the space around certain instruments was present.
A richness was also perceived, which was an addition to the authority of the performance.

The PC Triple C was the last up for the demonstration.
This was even more noticeable for the Clarity Perceived over the OCC.
There was a lift and lightness/finesse noticed to be present across the frequency range.
The off centre seat was also offering a insight into the performance with an added information, when not in the Centre Seat the performance did not appear to be at a loss.
The sound stage had taken on a new dimension.
Both the system owner and myself were of the opinion that the
PC Triple C has produced a delivery that is feeling much more real and honest when compared to OCC.
We were as a end discussion wondering how the combination of
PC Triple C and D.U.C.C would combine.
The thoughts were the Clarity of the two wires are very similar, the extra lift and dimension of the soundstage of PC Triple C, along with separation ability and rich tone offering from the D.U.C.C could be a wonderful marriage.
Additional Advice Required.
The Power Amp's as previously informed are going to be altered to be a Balanced Operation, swapping the Chassis Female RCA's for 3 Pin Female XLR's.
Unfortunately I am restricted by the engineers request to use one Connection Port, RCA Connection will not be available.
The suggestion is to reconfigure the Male XLR's if  unbalanced is wished to be achieved at some time.

I am trying to search out a High Puity Metal Female XLR to mount in the Chassis.
I have found Pure Copper with Gold Plating and Tellurium Copper with a Gold Plating.
The Types found with the metal above are not with a Locking Mechanism between the connectors.
Any thoughts on the Quality of a XLR connector/connection will be well received.
 
The Engineer has informed me that the New Cable to be used within the Amplifier will be a Microphone Cable.
I have been thinking this one over and a thought that has developed and not yet discussed with the Engineer, is if the internal wire can be a pre assembled Double Helix Design.
Any thought on adopting this as a approach will be well received.

A Pre Amp that looks like it will be my final Pre', had been on hold as a Build Project, due to having been loaned a version of the same design built as a Stereo Pre'.
My Pre Build is now going to be redesigned and produced as a Balanced Pre, some of the parts are already being acquired.
Again the XLR's chosen for the Power Amp will also find their way onto the Pre' Chassis.
If the Double Helix is a  Good Idea to be used within the Power Amp's then this again will be replicated within the Pre' Builds.
Any thoughts are welcome. 

It is proving difficult to find information on XLR usage reviews from comparisons outside of the sources of infoormation within this thread and the Links that can be sought.    
Steve
         Thank You for the pointers.
I will commence planting seeds in the EE's mind about the intentions for the internal of the Chassis.
The change to XLR is for myself a new concept and very little knowledge has been acquired by myself on the use of the method, be it connections or Cable.
The Tiger is taken  by the Tail and the journey into the unknown has almost commenced.
Pretty Typical to my usual attitudes displayed in the producing of my HiFi System.  
As an update to my search for Chassis Mount 3 Pin Female XLR Connectors.
I have found a part with a PC OCC a (Alpha) as the main pin.
It is a Furutech FT-786F, this type of part gives added confidence to the route I am taking, it is not too expensive either, and only two are required to commence the new set up.

I have extended my search further to discover PC CCC Wire that miight prove useful in the Double Helix Power Cord Design.

Acrolink do a Speaker Cable.
I have done a few searches over the past week and have seen used cable for sale at a not too extorionate asking price.
Shipping and Import will be required on most I have seen if exporting to the UK.
The Wire is available in 10 AWG and 14 AWG.  


Correction to my Last Post
The Acrolink Wire is D.U.C.C  
From  my most recent use of D.U.C.C used both on a Full Solid State System and now my own Full Valve System.
D.U.C.C Wire has tremendous capabilities at separating a singer and instrument and exgtending a Soundstage.
Between CDT and DAC the old used cable is completely relegated.
Between SUT and Phonstage the whole presentation becomes much more real and the sense of honesty has been further reiterated. 
PC OCC (Purity Copper - Ohno Continuous Casting) is a Japanese design for a Wire and has been produced under a Patent and known as the name PC OCC.
This Wire is no longer produced by Furukawa and is maily offered by Furutech who purchsed most of the final stock.

UP OCC ( Ultra Pure - Ohno Continiuous Casting )
Is made under the same Patent but is from another juristiction as the Furukawa produced Cable.
UP-OCC has not been stopped as a manufactured wire, but has been upgraded as a design to be UP-OCC a  (Alpha)
This is a cryogenic treated version that Furutech have become involved with.

Furukawa today offer PC Triple C as the replacement wire for PC OCC and the crystal structure is different in the Triple C.
It seems to work well wit Nano Treatment as to Cryo Treatment.

D.U.C.C
Is the purist of the modern wires, it is very different in the crystal structure to PC OCC, through the Crystal alignment, which are even more aligned by a In House Treatment which is referred to as 'Stress Free'
The name of OCC is given the name of the Professor Atsumi Ohno who discovered the Manufacture Process, where a Long Crystal was produced with the Wire.

I would assume if a Wire is produced with a Crystal Structure that is within the dimension that is outlined in the criteria for a Wire to be called OCC, there might be some ground for a challenge to be made.

There might be Wires Produced today that have a Long Crystal that is outside of the original OCC Specification, but when compared to a OFC Crystal qualifies as a comparison for it to be to be called OCC without too much risk of being challenged, especially if produced outside of the juristiction of the Patents.

Out of Interest, are the Five Patents known to have a end product of a produced wire ? and I wonder who the additional producers might have been.      
What Happens to the Audible Hum when the Morrow Audio MAP3 is put back into service ?
Is the Auduble Hum coming from Both Channels with an even volume,
or is a Single Channel Audible Hum ?

Ear to the Speaker time i'm afraid, to investigate this one. 
Good News, That your investigation of the Hum was located on one Channel Only and the Swapping over of the Tubes in the Channels showed the Hum problem had migrated to the opposite channel.

This is one of the benefits of using Valves in a System, by following a couple of Simple Preparation Rules, Valves can easily be exchanged.
Trouble Shooting to discover if a Problem is within a Valve, or if the Issue is Upsteram or Downstream from the Valve can be proven relative easily.

The Downside of using Valves in a System is that if a Third Party measuring device is not used to confirm the condition of a Valve, the use of the Valve is a done at ones own risk.
I have had 60 Year Old Valves give a reading that Measures beyond Factory Spec, and Brand New Valves that do not offer a reading to produce a Measurement.
   
The Speedy Access that you have to the Tube EE is a very valuable assistance, when there is a raised concern.

From a personnal viewpoint, especially after the reassurances being offered about the Helix Cable to support your inquiries.
I would put the Helix Cable back into Service and assess its usage for the Benefits that are bing Perceived.  
A little bit off topic, but relevant to wire types.
I have been quite impressed with the use of Phono IC's made with        PC Triple C Wire.
It has now replaced permanently a Silver OCC Wire IC.

A friend has been introduced my owned PC Triple C IC's and has expressed a very positive reaction, to the point they have imported their own cables.
Not bad for somebody who builds cables and is a close associate of another cable producer who has a following for their work.

The associate this weekend past was introduced to my friends imported PC Triple C cables used on their system.
I have been informed the impression that these cable made was something quite special.
I think it safe to say, that the PC Triple C wire can offer a rethink on the use of OCC and OCC alpha which is used by the two converts.      
PC TripleC /EX has a forged Silver Sheath onto the Wire.
It is not Cheap, SAEC are charging $900 Dollars for Tag Wires.

I have a length to Strip and produce Tag Wires and Tonearm Wires from.
I am also hoping there is enough to use internally within the Monoblock Amp's when they are modified to become a Balanced Design.
The Conductor Pins on these XLR Plugs as shown in the Links are in keeping with the Wire Choices being made within this thread.
There is Plating as an option to have additional protection as referred to as the preferred choice.
Not a Cheap Option on OCC at £ 90 for a M/F pair.

The Link is to a Brand I have not discovered in past searches.
That is the benefit of doing a search, the Robots throw other unknown products into the line up.
This Brand also does Mini XLR but I could not make out the lead out pin materials.
The one in the Link is looking likely that it is a Gold Plated Copper, as the specification refers to plating materials and Metals, where Gold and Copper are listed.  
What is very evident is that these are very competitively priced.

The idea of using differing purities of wire and wire production methods for the Signal Path is carried out by Audio Technica on their recent Rexat Cables.
Trying different configurations of Wires and Gauges as you are doing could prove to be the method to get a presentation throughout the frequencies that is to ones preference.  

I think this thread will always reignite, there is too much of good vibes contained within it to be overlooked.  

A friend who produces their own cables has a preferrence for for KLE Harmony Copper and Copper Wire.

When they produced a set of Cables for myself, I supplied the Silver AECO RCA and there was not any comments made on a significant perceived change to the SQ when they were hooked up to the producers system.

The Wire used was D.U.C.C and this had been perceived as having a added richness when compared to PC CCC.

The Silver RCA, might have impeded the full richness of the Cable being delivered ? 

@mbolek The Threads been quiet for a while, I have a question for you.

Did you receive your PC CCC  Wire Order?

If yes, has it been used and you have formed an assessment of it.

I have now been able to have been demonstrated the wire in use, from Source to Speaker on a friends system who I introduced to the wire.

The Vinyl LP as a Source on my friends system, now has developed to the wire being in use as an internal Tonearm Cable, Interconnects with Selected Low Eddy Connections on the Cables and Phonostage Chassis, Internal Phonostage Hook Up wire and the Power Cord, the Speaker Cables are also using the same wire.

This is a system I am very familiar with, and when presented as the system owner had wanted it to be heard, it was without doubt, the best I have ever heard this system.

I was gobsmacked at how a Cable that sounded very good when demonstrated, was shown to be presenting as quite inferior when compared to the same Cable ng with a different RCA Connector, especially a RCA selected for the Low Eddy Properties. This is indescribable and is needed to be experienced.

When the exchanges were carried out, the Low Eddy Signal Path was able to present Notes and Vocals with a Envelope Shaping, in a manner I don't ever recall being able to perceive.

The system owner has also made it known, the wire has created such a positive impression, if the wire could be discovered to be purchased in a gauge to suit a MC Coil, they would send a Ortofon Cart' away as a Donor Cart', to a rebuild service, to have the Aucurum Wire replaced with it. That is quite a serious move toward this wire type in anybody's assessment. 

The wire is available in very fine gauge 0.03mm as a Screening Mesh, but is only found in assembled cables, a 0.18mm is the finest I know of in a stranded wire. 

 

@mbolek It took almost six months for a package to arrive that I purchased from Australia, there may be a pleasant surprise turn up.

I do believe that a XLR is a low mass connector and the Eddy Effect is reduced due to this.

As you are an EE, the discussion seen in an old thread I have seen, where a method is proposed for producing connections that are said to be Low Mass.

The Link will show the discussions and selected parts for producing the method from the era, there may be a variant as an option today.

I am without doubt the improved impact on what I was experiencing is due to the choices made for the connection.

This was not a veil had been lifted moment, each Cable was appearing equal in Soundstage Depth and Width, and how a insight to a recording was being perceived, each Cable was able to deliver with a very similar presentation for the overall performance.

The difference was how the Note and Vocal took on a Shaping of the Envelope, the Cable with the Low Eddy RCA Termination, when connected to the Low Eddy RCA chassis mount connector showed a substantial and notable improvement in this area of the presentation. 

Does having the CCC Wire running through the Analogue Source Signal Path contribute to the effect, I can not say, but it does contribute to the perceived purity that is present in comparison to other used signal wires.

@mbolek Thank You for being a Pioneer for using the PC CCC as a Helix Geometry.

SAEC SL-5000 might be the closest Wire 'off the Shelf' to come close to this configuration.

I have waited in great anticipation for your report of usage and am quite pleased there are perceptions of improvements already detected. From experience I feel confident this will be built upon, as the real differences come to light when comparing to OCC Wire.

 

This is great news, that there is enough happening to already see if a little more can be extracted.

As said previously, the SPV-AV Triple C, was the Cable I had to give a Burn In Period.

Initially a short period was required to experience a gathered presentation.

After a Short Period of use and a A/B Comparison with the Cable it was replacing, it had already shown it was a alternative presentation.

After a revisit to A/B with approx' 1 Month of usage, the original used Cable was not in with a chance anymore.

I would suggest to stick with your creation for an extended period and get quite familiar, with what is on offer.

Individuals I have introduced this Wire to through demonstration. Now Have this Wire as a Internal Tonearm Wire, Interconnects, Internal Wiring in Phonostage and Pr-Amp, Speaker and Power Cables.

They have even gone to the expense of SAEC SL-5000  

    

@mbolek Hope the Holiday Period has been enjoyed by yourself.

As an inquiry, has the Holiday Period allowed for any additional periods of creating a assessment of the PC Triple C Wire in use.

On another forum that I not a member, but where I have been a influence of the use of this wire, I have seen a reference to SAEC XR 3000 Cables as being potentially the best VFM Cables.

As this individual making this claim has been demonstrated the SL 5000, with SAEC Supplied RCA's and Low Mass / Low Eddy RCA Connectors, they are used to the better end of SAEC PC Triple C Wire Cables.

The statement did not claim to be using SAEC Supplied XLR Connectors or an Exchange XLR Connector.  

@mbolek I have read the posts in both threads.

This report is with a content about the impression of the PC Triple C Wire that is quite familiar to me.

There are more than one way to describe the presentation from the wire, but when compared to a OCC Wire, the comments all are off the view there is a change and one for the better.

I stated in the past a further veil has been removed and this veil has allowed for a lucidity that is difficult to imagine can be bettered. There has been new micro details find a way to be audible from the recording. The one that really captured myself in my system was the Vocals of a Female Singer, the control used for the breathing had become tangible, it was a quite unfamiliar encounter when first discovered. All most like Q Sound had been used to produce the effect.

On a friends system who I have encouraged to use the Wire, there commitment to using it has been similar to how yours is looking to develop.

Wand Wire, Hook Up Wire, RCA Phono's, Speaker and Power are now all PC Triple C.

The experience I had of it with a Low Mass / Low Eddy RCA on Chassis and Cable was the best to date for me, the 'Envelope' of the note, was visual, the shaping of the Vocal and Instrument manifested in a manner not experienced before.

This is the most impressive and wanted to be reproduced trait from the Signal I can suggest to be is a worthwhile endeavour to discover how to be achieved.

If the intention is to continue the Signal Path as a PC Triple C Hook Up Wire, have a good think about the Chassis XLR, one temporary trial could be to direct couple the Cable to the Circuitry to see how the Chassis XLR might impact on the SQ.      

Monosaudio are producing Copper BNC Connectors.

I would suggest from experiences introduced to, it would be best to have the same quality connector on the Chassis as well.

@lemonhaze I have been an advocate of PC Triple C for quite some time now, along with another Wire D.U.C.C.

The amount of individuals now turning to Triple C in my locality as a result of my loaning the Wire for demonstration has increased to quite a few converts.

It is even now in use as a Tonearm Wand Wire by a few of the converted.

@mbolek has now used PC Tripe C to produce Helix Cable and his comments are found in this thread.

The usage period is now quite extended, he might be able to update on his thoughts on the Wire in use.

Whilst reading another Threads Post on this forum, I discovered the following that has a range of Connectors.

I have carried out many searches for Copper RCA and XLR Connectors and this site is a new discovery.

I hope it helps with a plan another may be putting in place.

When the System is reassembled, the intension is to be using this design of  Cable.

In the interim, I am having a few changes put in place.

The Power Amp's are to being returned to the Designer/Builder to be converted to work as Balanced and Single End.

Another EE Friend is now commenced with building a Balanced/Single End design of Pass Korg Nutube B1 Design Pre-Amp is being produced.  

The Power Amp' EE has asked for all devices to be in use, to be made available for the final testing to take place, as well as be supplied XLR Cables that can have a Earth Shield detached at One Connector.

The query is, does the Helix Design lend itself to this request from the EE.

I was not quite onboard with the EE's inquiry, when questioning me about the Cables to be built, I am interested in meeting the request from the EE, and to have a Cable available with this as a option, which will be able to have a shield detached.     

@lemonhaze I was quite taken with the PC Triple C wire.

Others I have introduced it to have given it a very good appraisal, and I have been demonstrated some of the designs been put in place for it.

As a Wand Wire and Internal Phonostage Hook Up Wire, it has left me very impressed.

I felt confident there was a place for it with the Helix Designs and am glad to have bought into this idea and the CCC Wire to produce these Cables.

@lemonhaze Thank You for your continued description on the perception of the CCC Wire.

I have the perception that CCC Wire as a standard Cable configuration cleans up the presentation in a improved manner over a OCC Wire as standard cable configuration.

When compared as a DIN>RCA Phono Cable the CCC Wire Cable Superseded a OCC Silver Wire Cable, the CCC was perceived as the wire that offered a preferred balance across the frequencies, notes and vocals were delivered with a improved substance to their envelope and was certainly the least smearing of the Details/Micro Details.

I would suggest that the two cables can be compared at intervals, after experiencing extended use of the wire types being used.    

My HiFi System is nearly all in storage at present, which results in my delay to produce the Helix Cable Design.

I have now offered a friend a selection of collected Wire to build the Helix Design for themselves.

In my cache of Wire, there is a Stranded PC Triple C/EX which has a forged CCC Silver Coating on the Copper Core Wire. 

This is one I was going to strip down to the strands and attempt to make a Tonearm Internal Wand Wire.
