In response to some questions I've gotten, this amp drives the DeVore Nines cleanly through >100 dB peaks and ~90-95 dB average (using Radio Shack analog meter, C-weighted, slow response) on classical (i.e. Haitink/LSO on Brahms Symphony No. 4), and high-energy jazz (i.e. Ron Carter's Dear Miles). There is no distortion or noise from the amp, dynamic snap is still there, and soundstage retains size and depth, even though it's much too loud for my room and louder than what I'm used to. It says a lot about this little guy.
