Tube Amps vs Sanders ESL Amp for Electrostatics


Fellow Audiogoners, I  am considering the purchase of electrostatic speakers and an amplifier. I am a fan of tube amps but due to my preference for electrostatic speakers that place special impedance demands on amps, I am also considering the Sanders ESL amp. Does anyone have experience with the Sanders ESL Amp and tubes amps for electrostats such as Martin Login etc. Thanks in advance for your feedback. Much appreciated.

Bombaywalla and Hew, thanks for your comments. I think it would be difficult and costly to find a good tube amp to work successfully with electrostatic speakers. That said in addition to Sanders and Coda high current amps I think there may be a few hybrid amps that make be suitable as well. As it is difficult to audition all the possible available amps, I am relying in part on the advise from my fellow Audiogon members. Thanks for your input. Regards
Roger Modjeski (Music Reference) is making an ESL speaker with an integral direct-drive (no output transformer) tube amp. I'll bet it's killer!
A lot depends on the ESL! Sound Labs and older Quads like the ESL57 and ESL63 are good matches with tubes.

Martin-Logans are designed (meaning they have a lower impedance but otherwise have an impedance curve typical of ESLs) to work with solid state; all you need to get a tube amp to run them might be a set of ZEROs (www.zeroimpedance.com). We've got customers that have been running our amps (which are zero-feedback OTLs) in this manner quite successfully with MLs for many years.
