After hearing and owning a few different tube amps. I suggest having a listen to Linear Tube Audio transformerless amps. I have the ZOTL 40 driving my Janszen zA2.1 hybrid electrostat speakers and it's the best sound I've ever heard. I believe Upscale has them as well as Urban Hi Fi.
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.
