Old thread and no responses. Sorry bout that. Did you get one? I have used one with there different DACS and that's about to be four and it's killer. Best money spent on the video side of my system. Even the blue ray sounds so much better than directly into the DAC. Love this unit and I don't even have the upgraded PSU for it. Someday as I know that would make an even bigger difference. I may have to sell it though as I will have the new Ayre QX5/Twenty in a couple of weeks and won't need the unit.
