I agree about the electrostatic speaker sound quality, I had a set of then vintage electrostatic speakers that I bought used and thought I paid too much for them in the eighties but they sounded incredible. They didn't have low bass capability but I had them on a crossover and ran sub woofers in my system which resolved that issue. Then in 89-90 a guy offered me almost three times what I paid for them, I wish I didn't sell them. They are the only speakers I have ever owned that were so clear you could hear on a master recording of Rush 2112 that the waterfall in oracle was synthesized.
You never pay too much, you just buy too early.
