Will 80 tube watts run MartinLogan SL3?

U will not get the full sound from ur speakers...try moderately priced high current high powered solid state. Nothing wrong with high powered Tubes, but they cost away too much. My suggest is to look into Adcom 5802, Classe over 200 watts, bryston 4b st, DNA, parsound 3500 etc.....with any electrostatic speakers, never enough high current power. better current better sound. My personal choice would be adcom and the classe to smooth out the rough edges in the highs and mids and make the sound more clear.

No, they won't. To get the SL3s to run properly, you'll need an amp capable of some serious current. It'll have to be stable into a load of about 1.5 ohms to get the sound they're capable of. That means you'll need Krell, Levinson, Aragon, etc. I had trouble getting Classe to drive mine. Never tried Bryston, but they would likely be O.K. I wouldn't recommend Adcom or Parasound. Remember, Wattage doesn't matter, the amp just needs to be stable into a really low impedence. Good luck...

ML says that the SL3's will run fine on either tubes or solid state. One other factor to consider is the size of your listening room. I have SL3's in a fairly small room, and at my normal listening level (usually below 90db), I get plenty of dyamics from my McCormack DNA .5, which has 100 watts/channel.
