What kind of amplification for Martin Logan SL3 ?

Olivier, you made a good choice there. I have the SL3's myself and found the biggest difference was made by the use of Alpha Core Goertz AG1 speaker cables in a biwire configuration. As someone else here mentioned, these speakers have a dip to about 1.5 ohms, which can strain almost any amp. The Alpha Cores somehow relieve (dunno how, I'm not an engineer) the strain and let the music flow. Find a dealer who has them or buy a pair and re-listen to your amp choices. I believe there are a couple pairs for sale here and at some other sites. You can also go to www.alphacore.com/goertz.htm and check them out. By the way, I am now using the Muse 160 and am very happy with it.

I am running two conrad johnson sonographe sa 250's and love it - gives you 260 watts under $2500 - great sound stage

ML speakers tend to like tubes. They show up the grunge in most SS gear. Try Melos or Quicksilvers. I have had good luck with both on my SL3s.

Olivier, I use two different amps. VTL 225 mono tubes sound great. I also use the new EAD Powermaster 2000 for HT and it rivals the VTLs. I go back and forth. Tubes have a little warmer sound and the EAD has incredible power for the bottom end, but also very detailed. Jerry

I am biased as a principal in the company, but Clayton Audio's S40 and M70 monos work extremely well with the SL3s. You need current and that's what you get -- pure class A (most so-called class A amps don't do full A till their rated output. Ours do.) We have sold several amps to ML owners who have tried many, many amps without success. Our amps were developed using MLs as a principal reference. Audio Adventure used our S40 (40 watter) as their reference amp with the SL3s. Audiophile producer John Marks has publicly praised our amps and he heard them with SL3s -- a speaker he normally thought was cold and dry. I own SL3s myself and drive them with M70s but the S40 works fine for normal listening. Look up our reviews (TAS, Positive Feedback, Soundstage, etc.). Or email me and I'll be happy to give more info.
