I have noticed some people looking for this DAC. I don't have direct experience with it, but for what it's worth, I do use an Apogee DAC in my main system, and I'll say a little about it in order to give an idea of Apogee sound quality.
My unit is a DA-1000E-20 with its matching power supply. There is no USB input. Its sound is really excellent. Lots of energy and presence, very involving, brings me one level closer to the music. A small trace of congestion and hardness in the upper midrange on complex passages, but this is only compared to very much higher end gear like the Cello Reference converter, the Ensemble Dichrono pair or a Linn CD12. It is also more forward-sounding than these.
Other than Apogee gear, I have been told very good things about the Presonus Firestation, an ADC / DAC / mixer which interfaces with a computer via FireWire.
