First, have to agree with calvinj that Clarity Cable is a very fine cable that on performance should have much greater place in the audio world, and very sadly it doesn’t.
Second, agree with dorkwad about the Schroeder Method, in my humble opinion it is one of those procedures that absolutely and conclusively shows how cables can have a positive effect on audio reproduction ( so obvious no double bind tests required ). Frankly, lo res, hi res, expensive, modest systems will all benefit from this upgrade. In fact, as a friend said, if you can’t hear the benefit might be a good time to find another hobby like golf, or something, anything that doesn’t require hearing acuity ( slightly paraphrased and explicates deleted )
And one more thing. Basically agree with geoffkait above about how system components in and off themselves can or cannot define how good it is at audio reproduction. At the very least until there is some discussion about the acoustic environment they are used in. Lets remember that the room is the most important audio component and which provides the largest contribution to the "sound" of a system ( some have pegged that contribution at about 50% ). Put a potentially great system in a crap room and guess what, there is an almost certainty that the great system will sound like crap ( with diminished ability to hear detail, nuance, and change, both large and small etc etc etc ).
