Just got my Teac AP-701 (used and broken in) and I must say that it is a very enjoyable listen; not 'warm', but lots of detail without sounding harsh, and plenty of body in the overall sound. A very musical sounding amp with great .
My only issue with it is lack of depth in the sound stage. I tried another class 'D' amp last year from a more expensive Devialet and had a similar problem, though I didn't like the sound overall as much from that one and it also had about the flattest soundstage I've ever heard; didn't even project from the front end of the speaker to the rear of it. I'm using an Aric Audio tube preamp so the problem isn't with that.
I was going to try to downsize and still get something I was happy with, but it looks like I'll be stuck with my 85 pound MSB S-200 that I am unable to even lift anymore for the forseeable future. Is lack of depth in the stage a class D thing or was it just the two units I happened to try?
