Which DAC as a preamp?

All valid thoughts folks...thank you.  Somehow...i think that this will be a bit more challenging than I first thought.

More good information folks...thanks so much. I will pull the trigger on something within the next day or two, and we will be off to the races.

Thanks for all the input folks. I ended up with a good deal on a nice peach tree sonadac. Small form factor like the amps...triggers them by remote....running balanced cables...sounds great. I am breaking the amps in, but so far I am VERY impressed with the red dragon amps as well. This may be my favorite system of all time!
