I don't have the XPA-2 but I do have the XPA-5 and it is excellent in all ways. Puts out 200wpc and is very refined and crisp at all of the levels I have played it at so far-both very low and probably way too high. Everything I have heard about the 2 is at least as good if not better than the 5. Apparantly the 2 is just massive in your face power although I think the same about the 5. I'm currently debating between the XPA-2 and the soon to be released RPA-2 for my 2 channel music.
