I bought Innersound electrostatic speakers about 20 years ago. At the time they were reviewed in Stereophile and given a class A rating. They are still in my system. I replaced one of the woofers about 12 years ago. Three years ago I replaced a transformer in one of the speakers. Roger Sanders guided me through both repairs and I didn't have to ship either speaker back to Boulder, CO. He still sells the speakers online. I can't recommend them highly enough. My power amp runs them just fine - VTL 185 monoblocks, best in my opinion in triode mode. My preamp is also outstanding - Presence Audio by First Sound. Emanuel Go still builds them out of his shop in Renton, WA and they can be purchased online. I've had a couple upgrades to the preamp over the years. They are not cheap but occasionally one can find a used one available on Audiogon.
Best luck in your search. If you like classical music electrostatic speakers are a great choice, wonderful transparency and dynamics with the right amplification.
