Focalfan, I think many of the Sunrays available are the result of changes in the US importer and Tidal dealers. I have heard these speakers and all that deters me is their price and size.
Your characterization of their sound was true in my hearing of them in the '10 CES, but absolutely not in the '11 CES. They reveal the electronics driving them and cabling. This is also true of the Contriva Diacera SEs, which I own. I hear none of the "characteristics of ceramic drivers" in my home or at the last CES with the Sunrays.
I have never been impressed with any of the Magico speakers and just cannot stand the Q5s at all. The Gamuts do impress me, but not enough to buy them.
However, I always believe that people's tastes, associated electronics, rooms, etc. make one person's opinions, even reviewers, irrelevant or at least demand the warning that this is only your or my experience.
