i'm one of the most anti-snake oil, audiophile bs guys there is. and the pass stuff is outrageously expensive. but i do think that someday one of those amps will be sitting on my living room floor (used of course). nelson pass is one of the few guys in this industry that actually seems to justify the "genius" tag placed on him. his stuff is super well made, beautiful, and he refuses to compromise in what he wants to put out (class A? really? the most "non-green" amp i can think of). and he still routinely puts out his circuit diagrams for the DIY crowd so you can build your own pass amp if you like. pretty damn cool.
