Good Luck with your investigations into this.
I have been an encourager of the idea of using PC CCC,my system when in use was being changed to use the Wire at all interfaces, with the only alternative being D.U.C.C, selected for a CDT>DAC.
My being an advocate for CCC, and prompting others with suitable skills, has resulted with an individual adopting this as a Wire within a Tonearm Wand.
CCC, has made a very positive impression and the usage extends to, Phonostage ' Internal Wiring, Interconnects and Speaker Cable, of which I have been demonstrated in use.
I am yet to be demonstrated their system with it in use as a Power Cable.
I can assure the impression from the use of the CCC as Tonearm wire, has been very impressive and will most likely be indelible.
The usage and reported benefits of CCC, has been slowly gathering momentum in other forums in the UK.
I am witnessing that OCC die hards, are changing their long-term commitment, and removing the veil that obscures transparency, that OCC shows, in an OCC>CCC comparison.
If becoming Wed to CCC, the usage further uplifts to a new level, when interfaced with Low Mass, Low Eddy, connectors, both on Cable and Chassis.
