best used amp for Martin Logan SL3's

Classe CA 200 (heatsinks on the sides), I used to run one with a Audio Research LS-3 (non-balanced version) w/SL-3's with really, really nice results. Both pieces can be had very rea$onably too, cheers..

I second Classe CA 200. If you can get the Classe 350 mono will be even better. In general, SL3 likes high current high power solid state amp. I have great success driving it with Theta Dreadnaught. McIntosh amps with output transformers are not good match, they sound soft and slow.

i used a Rowland 10 when i had sl3s - i thought it was a good match
