tube amps and electrostatics

Georgelofi, thanks for the link and I am glad that you found what works for you. So did I, and it's tubes with electrostats. This is an old story in our hobby and after many years enjoying it I have learned that one of the few things that I can consistently trust to tell me what's "right" is my ears.

"Frogman: Georgelofi, thanks for the link and I am glad that you found what works for you."

Like I said, I even liked the sound of tubes into ESL's, but when you hear the extension and dynamic presence that's missing with tubes once you've heard a "good" solid state BJT (bi-polar not mosfet) output stage amp into them with lots of watts and current, you will think hard about what's missing, but then maybe you like that subdued rolled off top end.

It's not what works for me, it's fact, and electronic maths made up of Ohm's and Kirchoffs Laws, there is no voodoo involved.

Stated by one of the masters of ESL's design Roger Sanders that I quoted from the white paper I gave the link to. Here again in case you didn't fully read it.

OK, George, you win; clearly, I don't know what live music sounds like.

I will go back to sticking pins into my tube sockets now.

Interesting (appropriate?) moniker, BTW ;-)

I have never heard quad esls have a dynamic low end like is possible with good full range dynamic speakers. I always figured that to be their inherent achilles heel, as is the case with planars generally. Have not compared with a good beefy SS amp though. I would expect some difference there I suppose, the question would be how much and what happens to all the rest.

I have heard some very good results with bass dynamics using es headphones, like Stax, so I have to think such things on a larger speaker scale are possible, at least in some rooms with some amps.

I tend to like tube amplification best though I would say with my Stax electret (not es) phones, FWIW. Of course, those use the custom Stax transformer box to help get things right.

Maybe there is a similar transformer device possible for use with large es speakers to help address the electrical issues?

Did not realize es speakers had those electronic properties. Sounds like you almost need some kind of extended bi or multi-amping to really get best results, more so than with most any other kind of speaker perhaps? OR maybe a Stax-like transformer box designed to solvethe problem, if such a thing exists?

I read the key to driving ES speakers effectively is high voltage. That is an attribute of Class D Icepower amps I believe.

Has anyone tried a high voltage Class D amp with ES speakers? I'm thinking it might be a good match.

As a SoundLab dealer, I have had the opportunity to hear many of their full range electrostatic speakers driven by many different amps, both tube and SS. While out of the price range of many, I have found that Ayre MX-R SS amps do a superb job, every bit as good as the best tube amps I have heard.
