Joe,
Thanks! I read several forums daily, I just don't post often. I have an XA-30.5 that is my winter amp, (I live in Phoenix). I tell any visitors (audiophiles & non-believers) it is the best sounding space heater I've found. It's in my system & on from November until April. My Rowland 625 is in the system & always on the rest of the year...
Bud,
I've owned the Pass Aleph P, X1, XP-10, XP-20, and XP-30. To me, the X1 eclipsed the Aleph, The XP-10 was noticeably better than the X1, and the XP-30 has just more of everything than the XP-20. I'd still consider an XP-20 for my second system, when I move from my current rental house to my next house.
Daniel
