I’ve settled on using Audioquest Rocket 88 speaker cables, Siltech Classic Anniversary 770i XLR from the DAC to the amplifier, the new Siltech Classic Legend 380D BNC cables between NDX2 to M Scaler and M Scaler to Hugo TT2. I use a PS Audio AC5 power cable from the wall into the amplifier. I use a Shunyata Venom V10NR cable to an Isotek Sirius power block (for source components). I use PS Audio AC3 from the power block to the NDX2.
The Rocket 88s were a surprise, I really didn’t want them, but the dealer really wanted me to try them and gave me a long term demo set. They improved a lot on my Blue Jeans cable which replaced my Chord Company Epic twins.
I used to use Blue Jeans cables throughout and Isotek EVO power cables - cheap and really excellent for the price. I wasn’t a cable person and I absolutely hate admitting this, but the change to what I have now is an appreciable improvement. I guess I don’t really care if cables do or don’t act as tone controls, so long as I enjoy what I’m listening to.
