This sounds like a good matchup. I did all the reading I could, but I am not sure which one would make the best studio front end. They have similar startup costs, depending if PT HD is a priority. I'm wondering if the Orpheus brings something to do the table more than just being able to connect via firewire. Has anyone used both of these units? Who wins?
Input monitoring / Disk Caching / 256 track capability [versus 96 with PT10 native] / 64 I/O on HD Interfaces [versus 32 I/O on Core Audio-ASIO with PT10 native] / Bullet Proof Rock Solid, low latency connection to the chosen HD Interface / VCA grouping / Surround Panning / Sync HD capable / The ability to open the HD licence on a laptop with a 3rd party interface / etc, etc, etc, etc, etc
