Tube Amp for Martin Logan SL3 3

ML's *love* tubes. In fact, this is the only way to open them up. There are lots of tube amps in the $2K range (used) that are up to the job. Anyone who tells you otherwise has either not owned ML's or hasn't compared tube amps and ss in their system. Case closed.

The combination of tubes on top and ss on the bottom certainly have loads of potential if the $2K price point can be stretched. Works with my CLS1's/Kinergetics SW800 set up.

I second Ed's opinion regarding the "stories" about how difficult these are to drive. In my experience tube amps have been far more capable and at ease in dealing with the impedance swings.

I've been using a Baron for the last six months with my CLS1's -- I particularly like it's adjustability (i.e. tube options are 5881/6L6's, EL34's, KT90's, KT99's), four settings for negative feedback, tube adjustments). I initially adjusted the tubes (various combinations of pentode/triode) for source material but also liked the flexibilty when playing with IC's. I've got things pretty much "dialed in" right now so I've settled on two-thirds triode and zero negative feedback. With the right associated equipment this is a very nice real world amp, especially for the money. I listened to other amps with more finesse, but at the time I was running the CLS's by themselves and the ability to adjust and zero in on the best sound won out. Now that I've added the Kinergetics SW800 subs run by a separate amp, I might consider other tube amps to run the panels. (Adding the Kinergetics brings CLS performance up to a completely new standard. Just amazing.)

I have had feedback from another member, however, who had problems with the Baron driving CLS II's. I don't know whether they were z's or not, which I think would make a difference. I think it's definitely worth a listen since your dealer is local -- maybe a demo in your system. The tri-tube upgrade is a big plus. If you pull the bottom panel you will see a note as to whether the upgrade has been performed. Good luck.
