I've had great success with the Rogue Zeus and my Thiel 2.3s.
Before going tube, my solid state amps were the Bryston 4B ST and the Plinius SA-102.
I've found the Rouge to offer a much more detailed and present midrange than the Plinius and far less grain than the Bryston.
While it has the lowest power rating than the others, the bass presence is satsifying. I beleive that is due to the overall better midrange offered by the triode setting.
