I have a DirectStream DAC and am totally happy with it. I also have a Stellar Gain Cell DAC, employing both the DAC and preamp elements, in a second system, and I'm very satisfied with it as well. I tried a pair of M700 Monoblocks and didn't really like those - they sounded rather thin.
I second the sentiment about their excellent customer service.
