DAC Recommendations

I'm looking for a DAC to use with my Bolder modded Squeezebox, that I run into a Behringer DEQ, then straight to my amps. I will also connect my Oppo 970 to it for movies.

I've tried a couple of the current "favs" without much success.
-Lite DAC AH, it was okay, not great. But it won't decode 2 channel info from DVD's
-Mhdt Paradisea, great midrange, but rolled off extremes and no "punch"
-Benchmark DAC-1, too bright/harsh for me

I also tried a TacT 2.0 digital pre with room correction and absolutely loved the DAC section. It was airy & detailed without being harsh. It threw a huge soundstage and had great dynamics. The problem with it is, I need a PC to run the room correction software. I only own a Mac and it's a desktop in another part of the house. As much as I liked the sound, I'm not going to buy another computer/OS just to run the room correction software.

Any ideas on where I can get a sound similar to the TacT, in a DAC for around $1k?

Thanks
