Defintely take a look at the Classe CAV 180 (Listed for $2800 recently on audiogon) It is 180 watts but the rating of watts is the most ambiguous topic in audio. Also the CAV 75 which is 75 watts x 6 can be used for 3 channels bridged at 150 watts and used with your current 2 channel amp. Classe is true high end over the likes of rotel etc...
Classe amps are built like tanks - My only other thought would be a Bryston amp which also lays waste to most others in that price range
