Ck, I agree that tube amps certainly do not control the bass like an SS (maybe a CAT JL2)but no matter how much I try to enjoy SS, it never sounds real to me compared with tubes. I recently had the Pass XA30.5 and it does sound great on its own terms and is surely one of the best SS amps available. I then switch to Music Reference or Atma-sphere tube amp and well I no longer have the Pass - tubes just sound better in almost every way, at least with my easy to drive Merlins. So I wonder if you conclude the Nuforce are better than tube amps under 10k, and your familiar with them, or you are basically oriented to SS and tight bass control. If the Nuforce competed with tubes I would certainly try it, but it would be a first.
