If you look at the inside of any piece of audiophile electronics it will not have the same kind of expensive wiring most people use for AC cables or speaker cables. Why?
Not so with Pass Labs or Audio Research Gear. My Pass Labs X350 Amp that I bought in 2002 was wired internally with Monster Cable. I’m sure their newer amps have equivalent or better.
ARC started using Litz wire internally decades ago. I rewired my ARC SP-6b with Litz wire back in the late 1980s along with better caps, resistors and a volume pot comparable to the newer ARC gear at the time.
