Last year, I owned a pair of Bel Canto REF 1000 monoblocks. I very much wanted to like them,great looks, nice tidy size, low energy, but I gave up after 2 months. Weak bass, nowhere the rated power output - and essentially the midrange sounded as if it was in a tunnel. I am exagerating a bit of course, but the conclusion is that I could never see myself living with those. Life's too short to give another class D amp a second chance in this century.
