Further, Audioquest, a strong advocate of wire directionality, is hardly a one man operation.I apologize for sounding rude, but please read carefully before you pipe-off. I specifically contrasted AQ as a "big boy" operation.
As to the rest, I don't mind your perspective a bit even though it is not my own. I am hardly an objectivist. I spout the old chestnut, "Not all things that can be measured count and not all things that count can be measured" more often than most people sneeze. I too bought into directionality of all IC's and cables. As I said, Chris Sommovigo made me less certain.
As to fuses, does the name Roger Modjeski ring a bell? Please (carefully) read this; http://www.audiocircle.com/index.php?topic=105425.0
