Mark, Thank you. This is not only looking very hopeful, it's looking affordable (at least in an industry where $10k speakers systems are "reasonably priced" :) ) Question below.

I see the clock outputs on the HDSP9652, but i don't see the clocks inputs on the Benchmark dac1 or the RME ADI-2. What am i not understanding? I'm looking at them here: http://www.sweetwater.com/store/detail/ADI2/ and here: http://www.sweetwater.com/store/detail/DAC1/ The specs of the RME ADI-2 look fantastic. It can even be powered by batteries which is ideal for a truly silent music background and dynamics and it also accepts 192k. Then again the Benchmark looks better :) Thanks again.
