What innovative, unconventional cartridge designs can you recommend?


Most cartridges have a stylus and cantilever where the transducer (magnet, iron or coil) sits on the far end of the cantilever.  What other designs are there?

I am mindful of two designs which put the business end right on top of the stylus.  The first is the moving coil (MC) Audio Technica AT-ART1000 which places two tiny coils, each 0.9-mm diameter, with eight turns of wire directly above the stylus.  Australian price is about AUD-7000 and there apparently is a newer model, slightly less exxe. the ART1000X.  This has square coils for a bit more output, and threaded mounting holes.

A downside is that stylus replacement involves a factory maintenance program and the Australian website page describing this service does not exist.

Another design is optical, exemplified by DS Audio's range.  While these still need a stylus to trace the groove, the signal is produced by reading the intensity of light produced by a Light Emitting Diode (LED) hitting two sensors.  Between the LED and the sensors are two 'shades' mounted above the stylus which change the amount of light as the stylus vibrates.  These cartridges need a special "photo-stage" to replace the conventional phono-stage which is an additional expense.

Australian prices including photo-stages range from AUD-2,150 for the DS-E1 to the DS Master 3 at approximately AUD-40,800, which is a bit outside my price range!  Where is the sweet spot?

What other way-out designs are there?

" Has it been easy to identify English Nationals travelling on a British Passport as being Passport owners who are Born British and possibly Welsh - Scottish - Northern Irish or English.

Or was it British Citizens not Born British, but have a British Passport through a British Descendant - British Citizenship - British Overseas Citizen - British Protected Person. I can assure anybody, not just @dover that identifying an individual as English from this group is quite a challenge as many are certainly not solely resident in England, they are itinerant and work in all British Isles Countries, to enable them to maintain their stay in Great Britain.

Not a challenge for anyone not living under a rock.

English folk are people who are from England.

Scottish folk are people who are from Scotland

Welsh folk are people who are from Wales.

When I meet someone who claims to be English, I assume they are being truthful.

 

It is really upsetting that @dover seems to have got caught up in a situation where racism and projection of ill will was quite noticeable towards another nationality. I hope this is not a case of 'Birds of a Certain Feather, Flocking Together'.     

@pindac 

Your comments are offensive.

Being English has nothing to do with race.

If you conflate being "English" with a specific race, then you are the bigot in the room. 

Your earlier post where you claim to not personally insult people is clearly nonsense.

Kia pai tō rā.

@neonknight As a contributor to threads I have posted in myself, you will have seen on more than a few occasions where @pindac has made it known to those who do not wish to experience posts made, are more than welcome to not read any content supplied.

That stands in this thread as well, Scroll On By the @pindac Posts. 

@dover I have no soul searching to do. I have no need to stand in front of a Mirror and attempt to discover whether I have a dislike towards anybody.

The daily rewards I have in life from interacting within a Multicultural Society with kindness, politeness, friendliness, is quite special to have as life experience, it is certainly one I wish for both friend and foe.

My pleasant personality is instrumental in having been invited to migrant to the UK's homes in the UK to meet their Families and their home Countries to meet their extended Families. I own Property in other Countries for this very reason, where I have accepted an invitation to meet extended Families.

Friendships have extended to unknown Families a few thousand miles away. Others have expressed kindness towards me through passing to me Litres of Spirits, given over the years as Gifts from individuals who have got to know me well and from some who hardly got to know me. Being Teetotal allows others to be beneficiaries of such acts of kindness.

Bigot is not the Cap sits with comfort on my head.     

@richardbrand Firstly when I get confused about audio, I have a few sources I rely on that are not typically using forums, who are sought out to give me an assistance with becoming better gathered in my thinking about a certain line of thought on a matter that sticks as being of interest.

One individual who is consulted with, is through a very long Career and prior to their retiring. Become a Design Leader for electronic circuits used in vessels that are part of a Countries Defence Strategy where when deployed are solely present to defend nations. Such an individual has been the mind that designed the circuits and protections for the circuit that enables a micro Voltage current to be sent uncorrupted over 150ish metres in an environment that is for from optimum for such transfer.

An individual with such a Career and who has also run parallel with that a passion for audio experiences where Vinyl media is the Source Material for near 60 Years is a very good contact to be able to converse with. 

This same person has over the years become a good friend and I visit him and his Wife a few times a years for social interaction.  

Through discussion I have learnt about Ortofon, and as you have recently discovered Ortofon are not shying away from showing their Technology in a very public exhibition.

What Ortofon are not doing is sharing their IP for the assembly and function of the Cartridge, which I am totally in agreement with. They invested substantially to learn such valuable information, why should it be free issue.

My friend has a through acquiring a substantial range of Ortofon Cartridges produced across the past 25 years took the opportunity to become much better educated with Ortofon IP.

Ortofon have their own Rubber Producing Sister Company that produces Rubber Compounds for the Medical Industry. It is strongly suggested Ortofon are the most educated Company on Rubber Compounds able to be selected for a Damper Role in a Cartridge. Ortofon also produce a large range of Black Coloured Rubber Compounds, which makes it almost impossible to identify when a different compound is selected across different models.

It is also strongly suggested that Ortofon are producing Dampers Compounds that are extremely accurate and the Damper Parts are identical in properties when produced from a particular compound.

The highly polished Replicant Stylus > Bonding Substance > Selected Cantilever > Armature > Coil Winding are strongly suggested to be extremely close in their  weights for each assembly for each Cartridge. The same goes for the Magnet and Poles.

The overall assembly is able to be fastened onto the Damper with extreme accuracy across Cartridges due to the extreme accuracy of each Compound used fir the Damper Part. The Tension Wires also have a methodology for anchoring them, that enables extreme accuracy to the force applied to each Damper.

The differences that can be measured across Cartridges for produced distortion that can occur through the placing of the Armature and how this impacts on the B Field / Flux Relationship is at it ultimate control when the FSE is used, as this serves as a Jig to create a extremely accurate alignment of the Armature across Cartridges, resulting in consistent distortion readings. If Ortofon then choose to leave the FSE in place, there is the optimised alignment and the effect the FSE has on the B Field / Flux, which is the next level of creating distortion readings that are much more beneficial for the End Sound being produced.

Hence, The FSE is strongly suggested as being a critical part for both Cartridges not with it as a permanent part and especially those that do have it as a part.

How other Cartridge Producers overcome the across Cartridge accuracy for Armature Alignment and applied Tension to a Damper Part. That may not be consistent in the Compound for each Damper part selected, is an unknown if they are able to meet the standards Ortofon are able to consistently create.

The outcome of such IP being utilised, is that Ortofon Cartridges as a result of being consistent in how the B Field / Flux is managed. Results in Cartridges with a a measurement with very close similarities for distortion produced and End Sound being closer to each other when heard side by side.
