Well I'm not saying you're wrong. I guess the main thing is we end up happy with our kit and the sound we're getting.Been there done it with cables, both analogue and for digital purposes. Most recently an Audioquest Cinnamon USB, which originally went for about £100 or so. I bought one NOS a year or so back, had to pack some stuff up a while back and ended up with the stock USB cable that came with the external hard drive. Months later I was marvelling at the sound only to go round the back of the stereo and...yep. The Cinnamon was in its' box. I tried it out with my usual four favoured test tracks and the differences were, well, minimal at best (which I guess is my way of saying that if both were delivering the right sound for the tracks played, then you couldn't easily tell them apart). The Audioquest went on Ebay a few weeks ago, followed not long after by a couple of mains power cables.
