Pass is a pretty easy brand to get home trials of in the US. What country are you in? I'm not a big fan of the Pass sound but I think I'm in the minority. One member on this board says everyone should listen to Pass, Ayre and I can't remember the 3rd, maybe Luxman, to find your taste preference in terms of type of solid state sound. I'd probably add something like AGD in there now too.
Valve amplification vs Pass labs
I'm running vac signature 200 monoblocks with signature preamp, thinking about possibly going to pass labs, has anyone made this kind of switch and if so what did you think?
