I remain an advocate of the SUT in use. I am also very aware of the additional connections required to be used, and know from experiences had there is more to be achieved on this area.
In other Threads, I have referred to the use of Low Eddy RCA Connectors on both Cables and Chassis of the Amp, where A/B comparisons were carried out with SAEC XL 5000 Cables and a Bespoke Built SS Phon's MC Input / Output on the Analogue Signal Path belonging to the Audio System used for the Demo's.
Experiencing the use of Low Eddy RCA connectors on the Analogue Signal Path, as a subjective evaluation was describable as being transformative for the betterment of the Audio System end sound, when used in the permutation of Low Eddy RCA Connectors and PC Triple C Wire, being used as the Signal Path from Cart' Lead Out Pins to Power Amp's and as Speaker Wire, I also believe on this occasion the Internal Cabinet Wire was PC Triple C as well, it it was not, it is now.
When my Analogue Source is once more set up, this type of permutation is the first of the changes to be put in place.
The PC Triple C Wire is to be used where it can be utilised within Devices and Low Eddy RCA's are to be added to Cables and Chassis in conjunction with XLR Connectors as another option. These connections will be in place on both the Power Amp and the Pre Amp design yet to be built. I am today convinced that having both options for umbilical's is where I want to be.
My suggestion made in the past and now repeated. Is that when the Warranty Period is no longer in place on devices and if the desire is surfacing to learn if additional end sound quality can be attained. The use of Low Eddy Connectors and PC Triple C wire in the Signal Path has great potential be the method to create the improvement desired.
