i guess im bumping this thread...
im listening to a Hilo right now, on loan from a local (seattle) pro audio dealer. it really is pretty damn awesome.
the detail and separation are incredible. everything is floating on an infinitely black void - there is just SO MUCH room for any sound that comes out of the device. it actually feels like each instrument is on its own isolated layer of perfect silence. every little detail is there to be experienced and scrutinized as much as you desire.
It occurred to me that in today's home audio market this box is very dynamic. it does have a phenomenal DAC and very good amp, AND a dead quiet, dynamic, pre-amp (could be used to drive some wicked powered speakers). And if you happen to be a vinyl guy that wants to archive, it has one of the very best a/d converters around. imagine this box, and a pair of dynaudio's or genelecs.. could be a pretty magical and compact setup.. damn..
im dying to try my hd650's on it, and just may need to buy a pair of high end cans. will be very fun to take to the next local meet.
