I recently purchased a demo unit of the Rhea SE. I had always heard it in a large open area of the show room, and had always loved the music. When I got it home, I was surprised how loud the unit is, audible at the listening chair. I contacted the dealer who said the unit is within spec, and that this is just a result of the amount of gain from tubes. I'll admit it sounds great when I'm listening to tunes, but between, it not just audiphilia, its really audible. Have ordered tubes from Jim Mcshane. Is this my unit, the design, or inherent in using all tubes for gain? I'm only tolerating the 56 db gain setting.
