Rogue Audio Sphinx also uses valves and gets very good reviews most places
It uses JJ 12AU7 tubes in the preamplifier stage and a pair of Hypex UCD-180 Class D modules in the power amplifier to deliver its 100 watts per channel.
I believe the Hypex class D modules are well regarded these days and are are used in other amps that seem to get good reviews (or though I can't name any off the top of my head).
Personally I wouldn't discriminate against an amp purely on it's class
I would certainly try and audition one if I was in the OPs situation, I would probably go for a hybrid design rather than all tube.... but that's just me. I would try and listen to some and make my mind up from that...
