Recommendations for tube amp to replace Plinius


I am driving a pair of Legacy Focus speakers with a Plinius 100 mk3. The Focus speakers have an impedance of 4 okms and a sensitivity of 96db. As such the speakers may be a good match for a tube amp. Any recommendations for a tube amp in the $2500.00 used market range? The rest of my system consists of the Placette passive pre-amp and a Cary 306/200 cd.

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.
I have a pair of Focus 20/20 and use the EAR 534. It is 50 wpc and has rca/balanced inputs and also individual gain controls for each channel. It is a beautiful amp with a chrome front. It is also relatively maintenance free as tube amps go. It can also be mono. I have two of these amps and really only need one to drive these speakers. It retails for $3595 and I would sell you one of them for 1850 shipped.
In my opinion, you are not going to be able to move three 12" (or are they 14", I don't remember) woofers very well with a low powered tube amp. You won't get a whole lot of bass out of them, as they require tons of current. I lived with the Focus since 1990, and have just recently replaced them. I was very close to getting a Manley Stingray for them, until I heard the two together. Thin, but great midrange.
I have heard the Plinius SA-102 and thought it was a great sounding amp. How does the 100 compare?
