Wonderful system, Mihalis.
I was at the Rocky Moutain Audiofest a few years back, and the two systems that struck me the most included Gryphon and Wavac equipment. Would you believe I didn't even make it into the Wavac room (Playhing Lansche speakers, which have an ion tweeter) because the room was so crowded, yet the sound from the door was so etherial that is struck me as among the best at the show; I've been drawn to try Wavac and Lansche gear since - some day..
The Gryphon rooms (with Mikado and Diablo, mated to Rockport speakers) were a particular treat. Both rooms were of identical size, with same equipment differening only in application (vs. absense of) passive Rives Audio room treatments. The difference was night and day, and I thought the first system, without treatments, was damn good. The Rives active room correction was available but turned off and deemed unnecessary for the particular room/applicaiton. Again, the Rockport and Gryphon gear stood out. From the few hundred rooms I tried, these two rooms stood out for me.
