I did the test. I built a special cabinet to be a Faraday cage, then used theoretically optimal 99.99% pure silver conductors inside teflon tubular insulators which barely contacted the conductors, which were separated by 50mm for near-zero capacitance. ETI connectors. Compared to premium microphone cable with ETI connectors. Difference negligible.
>>>>>Strictly speaking, that is not a scientifically valid test. That’s the problem generally with cable tests and cable comparisons. There are variables that are not accounted for in the test. Examples:cables not sufficient broken in; cables not cryod; cables’’ directionality not accounted for; the possibility of errors in the test system. Therefore I am inclined to throw your test out.
