I have not had a demonstration of a SAEC WE-4700 arm, I am not in a position to pass judgement as I would in nearly all cases, reserve any comments of performance and impression made until such a time as I have had a in the room experience.

Where I do form an opinion is that it quite an expensive arm, so at this purchase price, I would suggest a long list of Tonearms prior to producing a short list of Tonearms to be investigated further, if an individual is interested in parting with such monies as a purchase value. 

The SAEC arm, as I have made known before in other threads has used PC Tripe C wire was the internal signal wire and to my knowledge is the only commercial produced arm with this wire on offer.

I have been converting to PC Triple C and DUCC Wire in my system over a period of time and have offered demonstrations to others in their home systems. The outcome being that I have been instrumental in the changes of signal wire others have succumb to adopting.

One such individual has been prompted by myself to adopt the PC Triple C wire as the signal wire used on their design of Tonearm.

It took some time to finally materialise, but there is now a Tonearm I have received demonstrations of with PC Triple C signal wire, with the result being it one of the most impressive experiences I have been party to on a Tonearm design I have been witnessing develop over the past few years.

There are options for earlier guises of the arm to undergo small changes to the design around the mechanical interfaces, which I agree are beneficial to the overall performance.

The newly adopted use of the PC Triple C wire is the one I would promote as the must have element of the available design changes.

Another friend who has their own Tonearm design has now been informed that if they are not investigating the use of PC Triple C as their signal path wire, they may be selling their design short, not letting it deliver to its very best.

I am now hoping that a Cartridge is produced in the not too distant future using this wire for the coil winding, I am hopeful there is a diameter produced that will suit this purpose. 

Note: Furukawa stopped producing OCC Wire many years ago, but produced a substantial amount in advance of their departure, hence Furutech have been using this Stockpiled Wire in their Brand for numerous years. 

Furukawa own the Company Fine Chemicals and Materials, which carried out the R&D for the New Wire Material PC Triple C.

PC Triple C wire used in A/B Comparisons to both OCC and OFC has shown it to be substantially improved over OFC and noticeably improved over OCC.

To date, I have exchanged Phono Tag Wires, Phono Interconnects, Speaker and Power Cables. The entirety of the Loom is not yet fully exchanged but most devices have had the Cables attached to them and improved presentation has resulted.

My offering demonstrations of these wires in other systems has been very well received by the systems owners, and there are now others I know who have took to the use of this wire and have extended the use of it beyond my own.

There is as said previously a Tonearm with it in use as a Internal Signal Wire and it is also being used as the wire internally in anther groups Phonostages. I am wondering myself if it is worth the expense to have it used as the Hard Wire within my point to point wired Phon' .  

I have also introduced DUCC Wire as well, to learn if sharing the different methods for producing the wires can offer the system a presentation that is perceived as being beneficial and offering further improvement. 

I also have available the quite expensive PC Triple C/EX Wire but am yet to put this to trial. 

I have heard the PC Triple C used as a Power Cable which has been Cryo Treated and Nano Treated, during the A/B Trial, the Nano Treated has had the most impressive impact on the system used and the devices it was used on. The Cryo Treated Power Cable owner has acquired Nano Treated Wire as a result of the experience of the trial.    

The following will supply a description of PC Triple C wire.

It is based on the Furukawa technical materials prepared by engineers, not by audiophiles. The purity of copper obtained in this process may not seem impressive as the FCM website claims the percentage to be 99.996% or more. However, this material has a completely different structure than even the PCOCC copper. The thus obtained copper has been called PC-triple C, from ​​Pure Copper-Continuous Crystal Construction. In the final production stage, the conductors are subjected to an aging process, where larger crystals coalesce with each other, forming monocrystalline areas.
