What is the best SS used amp for $1k or less?

Cbman, you've got some really esoteric speakers. Those were built in the early to mid eighties as I recall. What a efficiency are those monsters? Do you know how benign the impedance curve is? Do they still have their original woofer surrounds?

I'm afraid I don't agree with Jpaik, I've found very large differences in the sound of various amplifiers. I certainly agree that the speakers do have a much larger impact on your sound than amps. However, a well matched amp will make the difference between competent and sublime if everything else is up to task of revealing the differences.

Any of the Classe amps (integrated or not) would be playing in that price range, give or take 100 bucks. Great little boxes with excellent build quality. And with you mentioning soft smooth tube like mids and highs, that's the first name that came to mind. Although it is a little power shy though with regards to your wattage requirements.

And theres always the T-Amp.. :)

Sweet Coda on agon now.Might be a 4 channel but could be used as 2,3or 4 ch possibly.
