What DAC for Theta Carmen

I want to use an outboard DAC for 2-channel CD playback with the Theta Carmen transport (digital direct into the processor for DVD). I've got a line on a McCormack DAC-1 Deluxe, which I demo'd and sounded great, but I was wondering if anyone out there has used any other outboard DACs in that price range, potentially with the Carmen, and what your thoughts are. Thanks.
Look for a Theta Gen Va. You can pick one up used for $1500 to $1800.
I'm not sure if this will help you Dbw1, but I'm using a Theta Pearl transport with the Bel Canto DAC1.1 with very good results. The overall sound is huge, detailed and fast without being harsh. I like the combo a lot.
