Got the chance today to compare the Apogee Mini Dac with my Arcam rDac. The Apogee came in the version without USB or Firewire so I used a optical cable direct from my iMac. The Arcam was connected with the iMac via USB. I used iTunes and mostly WAV or Apple Lossless Files, listening only to classical music.
I switched lots of times between the 2 DACs and I have to say both are very good (at least in my ears). At the end I voted for the Apogee (even connected only via optical cable) as the whole music had little more punch, little bit more details and colors. But the maybe biggest difference was the soundstage. The Apogee offered a much wider soundstage than the Arcam did.
No deep gaps between the two candidates, only sometimes small details ... but they make the difference.
To me the Apogee is the winner, would be interesting how it would sound via USB or Firewire.
