Try not to despair too much.I, for one, couldn't care less if Obscene Audio charges $50K per foot for a USB cable. No skin of my nose! Even if I could afford it I wouldn't bother (law of diminishing returns). And if the Obscene guys bilk the 1%ers so that they can feed their families, more power to 'em!
Meanwhile, my experience is that cables and wire *do* make an audible difference. I heard really nice improvements with better speaker cables and hook-up wire. Less so but still worthwhile with interconnects but only tiny differences with power cables. To each their own.
