Yes, I had ESS Heil amt's back in the 70's. One of the best if not the best speakers I ever owned. The amt driver was the best tweeter I've ever heard. Crystalline, clear and a lot of air. The build quality, wood cabinets, beautiful. I'd actually forgotten how good they were. Caveat: I have not heard the modern ESS Heil speakers, but if I were you and had experienced "awesome sound" as you say, already, I would give serious consideration to a purchase.
