I have dropouts on a Pi running Raspbmc and a DAC from the recommended list of "compatible" DACs. It ran fine for a while, but ever since a software update of raspbmc (which happen frequently), I get dropouts when using the external DAC.
I consider myself somewhat competent in Linux. I tried tweaking quite a few settings, including audio buffer sizes, to no avail. I could reduce glitches substantially, but not eliminate them completely.
Based on my experience, I'd recommend something more powerful. Even a 2 1/2 year old smartphone like the Nexus S scores roughly *three* times as high as a Pi in single-threaded CPU benchmarks. I realize most smartphones won't work unless you got good WiFi coverage and the smartphone has decent line-out quality (or works with external USB DACs). I just wanted to mention this to put the really low performance of the Pi in perspective. Of course, the upside of the Pi is that it has a huge community.

good points, which seem to be addressed with the Raspifi distro, as they write in their project page (http://www.raspyfi.com/project/).
