Classe Audio -- Is My Amp Any Good?

Hi -- I know nothing about higher-end audio. I recently purchased a Classe Audio DR3 Amplifier (manufactured about 1985). I assumed -- perhaps incorrectly -- that this was a good product, given how impressive it looks etc.

My questions are this: (1) is this a good amp? and (2) what would be a good, but not expensive, pre-amp to pair it up with? I'd like to spend less than a grand on a pre-amp, and am indifferent on new vs. used.

This will probably make many of you ill, but all I want to do with the Classe Amp is have (I hope) copious amounts of power to power my 1992 Mission 765i tower speakers. And I plan on running digital music off an IPod (very primitive, I know).

Can anyone tell me if this amp I bought is any good? And give me a good recommendation for a pre-amp which I can run my IPod, and perhaps a turntable, to?

THANKS!
