Amps suitable to run Martin Logan SL3's


Amps from the Counterpoint old line or Audio Research suitable to run these speakers. Tube versions preferred.
Thoughts and/opinions.
Thanks, Randy

My Counterpoint SA-220 worked very well on Maggies. You can also upgrade the old units very easily and install better mosfets that won't blow.

Happy Listening.
I used VTL 450 mono blocks. I tried the Counterpoint Natural Progression Monoblocks and they were wonderful. The Innersound ESL amp worked very well. I expect the Audio Research VT 100 or something similar might work. The thing you need to watch out for is the low input impedance in the treble. I think the SL3s go all the way down to 1 ohm.
Thanks guys, Just the type of info I was looking for. In the early stages of research for building my system with a budget.
Just kinda focused in on the Martin Logans as there used prices are reasonable. Bang for buck wise.
Originally had my heart set on the Counterpoint SA 5.1 as a preamp and was getting ideas for the amp to use with it. But after spending hours researching it. I think the used prices are out of my budget for that preamp.
Second choice I believe is going to be an Audio Research SP6A or B.
Just to let you know where I'm headed with this.
Thanks again for the input. Much appreciated.
Randy
