Recommendations for tube amp to replace Plinius

I think there is something made by Antique Sound Labs that uses the 845 tube single ended for about 22 watts per channel. A friend uses one to drive his Silverlines.

You may be happy with Rogue amps, not the most revealing, but very nice sound.

Music reference RM-10. This is under your budget as a new amp and just got a rave review in Sensible Sound. I use the RM-200 and love it.

Being there with Plinius 100 mk3. Went with Mesa Baron, and Dynaudio Countour 3.3, and went back to Plinius! Plinius is fantastic amp, especialy in class A operation. What would you like to achieve with changing of the amps? I gained little bit deeper soundstage, and more liquid midrange, bass was good too, but not as good as with Plinius. I would look into better tube pre-amp, before i ditch Plinius. If you want tube sound, try Pass Aleph amps!

I'd try the Sonic Frontiers Power 2 I just happen to have listed. Shameless plu, and I'm willing to give you a more in budget price.
