Well, as I learned from BRM machine, make sure you put the pre-amp part of the equation to bed first. I really felt it made a bigger difference with my SS8's than my amp.
I'm currently using the Classe SSP800 and an older CA5200 combo. I really like the combo it's spectacular.
That said, I really like the Butler Audio Hybrid Amps. If you could find a couple used MONAD mono-blocks, those are awesome, their 2 channel 250 watt amp is also great. I had their 5 channel 5150 and it was really nice and sounded great with the SSP800. I could have been happy with that combo, but the chance to match the look of the Classe stuff was too much to pass up. The 5200 is also an older but great amp. I didn't want the 5300 from Classe as I tend to hate fan cooled anything.
But, those Butler MONAD's are awesome. Sometimes they come up for sale on Audiocircle and Audiogon.
Good luck!
