Anyone using Apogee MiniDac Firewire & Pure Music?

I see on their website that Apogee Duet, Ensemble and Rosetta have been used successfully but no mention of the Mini Dac Firewire.

Is anybody having success with this combination? I'm particularly interested in the automatic switching between different resolution tracks, especially 176 and 192.

There is a free trial!
I guess I could just try it.

Nice system! What DACs did you try before the Weiss?
