What kind of power needed for Martin Logans?

You never told us which Logqans you want? Also the Bryton and the B&K are not a good match with martin logans. They are both very cold and analyyical sounding.(sorry) Martin Logans are very sensitive to components that offer those qualitys.When I had my Logans I had Aerius i, SL3 and Accents I used Mark Levinson 335 or my new Krell FPB 200c which both sounded very good But I sold the 335 and now own the 200c I cant have them both if I could I would because they both offer very nice things to the logans. Krell used to be very harsh now they are more on the natural side but can still be a bit harsh if you dont properly match wires and other components.7 out of 10 dealers who carry Martin Logans use Krell on them so it is a safe choice. But be very careful how you match your system or you will very unhappy. Best of luck " Stand United"

Also I know use a B&W N803. One day I turned my system on and didnt like the Planar sound anymore. My system is Krell FPB200c Mark Levinson 39 and the N803 with all Harmonic Techs.

I quess I'll give a different perspective. I own Aerius I. I've been using them in a very small music room (12x12X9H)very successfully with the Audio Research D-130.

Fairly recently, I caught the SET bug and purchased a Cary CAD 300 sei (300b output, pure class A tube, 15 watt per channel) I thought I would move the Aerius into my home theater, until, for the heck of it tried them with the Cary. I know everyone is suggesting the biggest amp you can get, but honestly, this combination of tube and Aerius is wonderful. My room is small, but I tend to listen in the mid 85 db. At this rate, the Aerius is only using 1 watt or less. This is the most rythmic and musical combination I have ever experienced. The base is stronger but very defined and full. The midrange just sounds more "real" to me.

If you read the review of the VTL tiny triode monoblocks (25 watts per channel), http://www.onhifi.com/product/vtl_tt25amplifiers.htm,
you will find that Gayle Saunders (ML's President) uses Aerius and these little VTLs in his home.

So don't rule out tubes. You might consider putting the left and right main speakers on a tube amp in your setup if you use Aerius I and keep your room size reasonable.

I know the Aerius is easier to drive than most of the other ML. Tubes may not be a great option with the larger speakers.

Well, sorry to dissappoint, but I feel that the room I use for home theater might be just a little too small to accomodate the MLs. I have now begun auditioning other speakers, Vienna Accoustics, B&W, etc. Wish me luck.

I use the Wolcott Presence monoblocks for my SL3's..these are my second pair of ML's...tried a few amps, moderately or high powered tube amps are the way to go.
