Amp/ preamp for electostatics and why

The Threshold T series amp and pre amp work great for my ML's

I have Innersound Stats and amps. Roger Sanders designed the amps specifically for stats. Absolute glorious sound, They should be on your short list. Stats are a unique load for an amp.

I have the new Sanders ESL amp with my Martin Logan CLSIIA. I've tried many amps and kept this one.

Tube preamp wise, I've had excellent luck with Audio Research, Modwright, Cary.

As soon as I log off here I'll check out the martin logan forums. What I was mostly concerned with is the amplification as the PSE's seem underpowered for the SL3's. Also, they are not made anymore and would be difficult to have repaired. That being said the system sounds wonderful, I just have to have the volume cranked to 3/4 to get decent room level sound.

I believe that tubes add warmth and life to the rather lean character of logans.

The difference was rather pronounced when I went from solid state to tubes on my ReQuests. A buddy borrowed my tube amp to try on his Maggie 3.5's and sold his solid state amps and bought Cary V12 monoblocks.

I understand your concern for power as I had to go from a cj 11a to 12's to get dynamics and control. I have no relation to the seller of the set of 12's on sale here now and do not know your budget but they are fantastic reliable amps and have grunt and soul.

I moved up to Summit's as I really like rock music and the powered woofers let the 12's loaf but tubes and stats (to me) go together.

Have Fun!
