You should try the Metrum, right now, when paired with Focal SM9, my system blows away $50k audio show systems.
It's so simple too, Metrum Pavane, Focal SM9, Neotech XLR. That's it.
Of course, I back up the whole setup with balanced power, and a reclocker (although I may not need this anymore, it was to compensate for Directstream's crappy jitter rejection, or lack of)
