Blue Circle BC2 is a hybrid tube design and really should not be compared to a solid state design like Clayton. They are really apples and oranges. The Clayton is a high current solid state design that sounds as good as any solid state out there is the price range. They are as accurate as any amplifier that I have heard. They are designed and voiced around classical music. Several reviews that are good to read can be found at ecoustics.com. I would suggest you listen to them to see if you like the way that they sound. They have some of the tightest base that I have heard and no grain at all in the higher freq. The only preamp that they won't work with is a passive preamp and from there you need to try before you buy. The reviews have said that the midrange is "tube like" but I have read that about many solid state amps and don't hear what they are talking about. They are as true to the music the way it was recorded as any amp I have heard. Also check out the reviews by the owners of these amps on Audioreview.
