Hyperion HPS-938 speakers. Open, vivid but natural and relaxed/musical sound (with class D amp) - just opposite to Hi-Fiish sounding speakers. Incredible midrange. Uses speakers without suspension (spiderweb). Midrange 6 1/2" is damped with ferrofluid. Very tuneful bass with very low distortion and natural sounding string attack and decay.
First class imaging. Crossover integrates speakers so well that it is difficult to hear transition between them. I can hear extended and natural highs but cannot pinpoint tweeter alone. The only thing is that the are ugly - I mean UGLYYYYY... (but slowly growing on me).

Hyperions are indeed very good speakers! Very natural.

An eight ball before The Dead pulled out "St Stephen" at The Garden in the 80's. (I think it was the 80's)..........
