I once auditioned some AQ cables in a full Mac system that I would judge as pretty damn good.
I wouldn’t use Mac gear to assess any cables. They have a house sound that boosts tonal richness and rolls off the treble, which is why they’re often paired with B&W IMHO. It’s surely an attractive sound to some, but it’s a far cry from neutral and thus not a great vehicle for assessing the finer differences between cables.
moving from the $6k pre->amp IC to the $12k, the system became UNLISTENABLE.
So, you’ve shared one experience where a more expensive PC was supposedly inferior (lots of variables at play here BTW) to a “cheaper” $6k cable. Good for you! That means nothing. A lot of people throw around the term “confirmation bias” quite a bit here, but there’s another type of bias that also crops up here frequently, which is the representative bias. It’s when someone is exposed to results from a narrow sample sample or what they saw themselves a few times and extrapolates those findings across the board. Sharing one example of anything proves and means absolutely nothing.
