I have to agree with the other guys. The AMT 1 was somewhat overated when it came out.Also, that Heil transformer was in my opinion was a step backward and hurt this company.Before Dr. Heil took over, ESS made a line of speakers which used standard drivers, that is, KEF drivers from England and I think Vifa tweeters from Denmark. They produced about 5 models. I owned the ESS 7 which to this day was the most exciting speaker I've owned. I am sure some of this is just nostalgia. But they were clean,fast with outstanding bass response. I would look around for these models, someone may have a mint pair to sell. If you can't find them, spend you money on PBS, Paradigm, or even the new Tannoy Revolution 2 speaker reviewed this month in The Absolute Sound. Good Hunting!!!
