Also, take a look at the Aronov LS-960 and the LS-9100 monoblock amps on aronovaudio.com.
A used pair recently on sale for $1900 here on Audiogon. A stunning bargain price; not sure if still for sale, but worth checking if you want to avoid that restless feeling any time soon.
I realize you want the best, although you cautiously used expression "decent sound," and each of the earlier recommendations really excellent, but Aronov surprises in a special way. Aronov bass is hard to equal for tube amp, or any amp. Have heard a lot of the great amps at the NYC Stereo shows, and still not restless, myself.
