The best electrostatic? It does not matter. Compared to any dynamic speaker, they are all musical wonders. I have listened to my Acoustat 2+2 speakers for over 14 years and I have never tired listening to their sound and the wondrous music they produce. They best work with tube electronics that is for sure.
Best Electrostatic loudspeaker?
Many of us have found that nothing make the magic happen like a pair of Electrostatics. It's been an evolutionary road for me, starting with various dynamic systems, then ribbon/dynamic hybrids, then full range planar magnetics (Maggies), then Electrostatics. So those of you with experience in Electrostatics, which do you think is (are) the best designed and executed example(s) of the breed?
