I've found a couple of used Classe CA201 amps for sale at a good price. I've read some good reivews and one average review from stereophile magazine which usually gives every thing a good review. Stereophile called it a boring amp. Of course they were comapring it to Krell and Ayre amps. They did say it had more of a tube like sound and it was very detailed, transparent and imaged well. I've read some user reiews on other forums and many prefered it over Bryston, CJ and McCormack amps and they seemed to contradict what stereophile had to say.
