I didn't include the Weiss DAC204 on my list below because of the low'ish price and because I haven't heard that much about it. I do however like the simplicity, and that you have a choice of 88.2 or 176.4 kHz sample rates, which are multiples of 44.1, instead of the more typical 48kHz and 96kHz.
I did look up Michael Lavorgna's review at Twittering Machines and thought his comment below regarding the Weiss DAC204 compared to his totaldac d1 unity was a good description of one of the main differences I often (but not always) hear when comparing moderately priced gear with much more expensive gear, and also answers a question that often arises on this forum being, what do you get for more money? As he implies, even little differences can affect the level of listening enjoyment. He wrote:
"Finely detailed and as sweet as honey, the Weiss DAC204 proved to be more than up to the level of refinement this system has to offer and the main difference I noted between the $2895 Weiss and the > $12k totaldac d1-unity was one of body and weight—the totaldac imbued music with a greater sense of dimensional structure making everything sound a bit more full figured, more fully formed and fleshy. While this difference wasn’t huge in ultimate terms, I find when I’m in the listening zone even minor differences can be important."
