Sorry, I spend some time on the Steve Hoffman Forum, and probably posted there. As to your questions, I like it a lot, and have used it with several sets of speakers, including the mentioned CW4's, but also Rogers LS3/5a's, Joseph Audio Pulsar 2's, JM Reynaud Bliss Silvers and Cantabile Jubilees, and Klipsch RP600M's. I've tried it with low sensitivity LS50's, but didn't like the combo as much as with the higher sensitivity speakers. I do feel it is good value, and I plan to add the DAC option, but am sort of waiting for some reviews, but that may take awhile. Compared to other integrated amps I have, in its price range, I'd say it is my favorite. Those include a Hegel H160, Naim Nait 50, and a Sugden A21 SE Sig. As to what I would change about it, nothing comes to mind, but I'll think about that a bit more, and let you know. Oh, and my room is a large open design of 20'x37', but remember, I'm using it with CW4's, so they fill the room with music, no bottleneck with the Moonriver. I'd say its strengths are tonality, midrange purity, decent bass, and music just sounds right to me.
I do have tube preamps, poweramps and Ganfet monoblocs, so my view is not restricted. I feel it is the equal of them all, when paired with speakers of medium to high sensitivity. What more can I tell you?
