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.
