I had a lengthy litening session with the 3.7s at RMAF. I loved them. A possible gotcha is the type of electronics with which they are driven, which is usually the case,of course. I first heard them being driven by Brytan electronics. They sounded good, but with some hints of top end glare or courseness. After that, the rep switched them over to a stack of Simaudio electronics, including the W7 stereo amp. They sounded really good! The top end was not what you'd call warm, but was not sterile. It was brilliantly clear with loads of subtle detail. I'm currently shopping for speakers and if I can afford just a bit more, I will give them very serious consideration.
