Another possibility might be the second generation Krell KSA 200, which I believe ran mostly in Class A. But be prepared to have the amp re-capped, if not done already, as Jmcgrogan2 mentions.
Recommend Class a Amp
This past weekend I purchased some Infinity QLS-1 Speakers and the gentlemen I bought them from was powering them with a Krell KSA-250. I was impressed, how the Krell drove those speakers. Most of my amps are tube and I would like to get me a keeper used well thought of class A solid state amp. I would like to stay in the Under thew 3K price range. Look forward to your recommendations.
