Using tube amp with electrostatic speakers.


Moons ago I started similar discussions and thought I had been given enough good advice not to approach the subject again. Here goes anyway. I've used Martin Logan electrostats for well over 30 years with quite a few different amps but have recently switched to a tube amp and dynamic speakers with which I am very satisfied.  It consists of the Cary Rocket 88R amp and Serie Reference 3 speakers. 

My brother was visiting last week and was so impressed with the sound that he decided that he might want to try a tube amp also (probably the same one as mine).  However, he is using a pair of SL3's that I gave him years ago and I'm concerned primarily about the current requirements of the Martin Logans as well as other concerns that I'm not thinking of.  I don't want him spending money on something that may not bring him improved sound so would appreciate more advice to pass on to him.  He currently uses a Rogue Audio SS amp with his SL3 speakers and, to me, it sounds very good.

If you plan to use Martin Logans with a tube amplifier, you will want to investigate getting a set of ZEROs (www.zeroimpedance.com).

These will help that tube amp play the speakers without high end rolloff.
It’s not like the end of the world will happen if you go with tube gear, and different tube gear will yield different results.

If you randomly picked out a half dozen beefy solid state amps and equal number of beefy tube amps though, you might find 1 tube amp really does justice to the midrange and treble they are capable of, while almost all the solid state amps would.

However, if you are up for the challenge, you may very well find something you really like. :)

Personally, I would try to make my life easier with a nice CJ pre and a very solid SS amp, like a Sanders ESL for instance. That's just me, and my lack of desire to look very hard though. :)

Tube amps or tube/FET hybrids, work best with electrostatics IMO.

I have never heard the Sanders.

Why do you keep pushing ZERO?

Are you PAYED BY THEM?

Most all tube amps use output transformers with impedance taps that work just fine into 4  or 6 or even 16 ohms!

The Zero is of NO VALUE to most tube amps!
