Great system!
I'm assembling a system of my own currently with quite a few similarities. My question is: a friend of mine who's selling a pair of W/P8s told me that "The Pass XA-series of amplifiers are designed for stable 8-ohm or higher loads, the WATT dips to below 2ohm at certain frequencies.The WP8s work better with the X-.5 series amps like the X-600.5 monoblocks." Thats putting me off the XA, and made me look at the 350.5 like yours.
Do you agree with that? Also what do you think of new Pass XP-10/20 preamps?
