best used amp for Martin Logan SL3's

Wkjeffers, lots of amps will be good or bad depending on impedance, and because the SL3s go down to 1 ohm, they will test a lot of amps. Having used an amp which could deal with it on my SL3s and an amp which couldn't, I highly recommend amps which can!

I did not own one but I tested one before making the decision to go with big power tubes and I can recommend the Innersound ESL amplifier. I also liked the way Counterpoint hybrid/FET designs sounded with the SL3s.

thank you very much for the info.

The Aragon 8008BB will drive anything and can be had for less than $1000 used.

Great speaker! Something with high current and stable into a low impedance will do nice. YBA amplifiers have very high current (even though "watts" rating may be considered low) and are stable driving low impedance loads. They also sound fantastic with SL3.

I am running mine with a set of PSE Studio V monoblocks and it sounds really sweet.My only complaint is that its a little bass shy and I've got a feeling that's the speakers and not the amps.The PSE's are 120 watt SS mono's.
