Amps suitable to run Martin Logan SL3's

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.

Thanks for all the input gents. My main source is going to be a turntable. So the phono stage is important.
Mofi,Luv your handle.
T_Bone, Familiar with low impedance's. Quick story. I sold stereos at a place here, Called Hudson's Audio for 13 years. We had a pair of used Apogee Scintillas on the floor being run with Krell Mone 160's.
A guy walked in one night and wanted to here them with his Nakamichi Stasis Amp. I told him it would not run them. He insisted on hearing it. I handed him the lug wrench to disconnect and hook up his amp. Told him, You're on your own. He said it will be fine. My reply. I hope it's under warranty. And left the room.
He put Roxy Music Avalon on and cranked the Krell Preamp to about 12 o'clock.
About three minutes later. The room went silent. I walked in and smoke was pouring from his amp.
Love those told ya so moments.
I'll take all your thoughts under advise. And again. Thanks for everyone's input.

Just bought a Counterpoint SA3000 and a SA220 from a gentleman on here. Not exactly what I wanted. But as you guys know. There's always an upgrade path. This should do the trick well for the time being. Time being=waiting to accumulate more money.
Thanks again for the advice. I hopefully should be able to get the SL3's in the next couple of months.
