Chazzbo, Audio Physic Tempo's sound fine at lower volumes. I have a pair (the original Tempo's).
They also sound fine with tubes. I'm currently using them with a Music Reference RM-200 and an Audio Research VT-100 Mk2, but prior to that I drove them very well with Audio Valve ppp45's and a Jolida 302b. The Jolida was pushing it from a power perspective, but actually sounded quite nice.
In general, I've found the Tempo's to actually sound better with tubes than SS. I can't speak for other Audio Physic models, but can attest to that combination.
