I had the Dacmagic 100, quite liked it (unlike their Dock), holding up pretty well to more expensive offerings. Their customer service was not so impressive, when I asked about USB2/async since it was advertised but not showing up as an option on my Mac, they seemed almost offended to have to point out the sorta-secret button combo to enable the off-by-default feature (as per SuperiorTramp's post above, and quite hidden in some paragraph in their online manual)
But I'd say, after doing a 4-way switchbox (instant) comparison between DACs I had at the time, the DM100 is neutral rather than warm, not cold or analytical really, but not really warm either since that's what you seem to be interested in.
An option that was more along those lines, at a similar pricepoint, was the Maverick Audio Tubemagic D2, I really liked it, and it comes with both a solid-state path & output as well as the expected tube path & output so you actually have a choice. The solid-state output was very close to the DM100, but the tube output was certainly for once clearly warmer. Ultimately since I ended up using tube amps, and that was too much tube in the path for my taste, but before that I really enjoyed it.
There's a forum topic here, with my impressions at the time, but it's been quite inactive, since, like the Dacmagic, it's been out for a while and not exactly high-profile...
