The people at Auraliti might not be able to respond to all questions, but the PK90 is a fantastic device that removes all the settings and guesswork from a computer based setup. I have had mine running since September and I love it. It's a small box, and you hook up a hard drive and a DAC along with a router and laptop. Well, I guess it's a bit more complicated than a "turn-key" all-in-one, but it is just like the Bryston only 1/3 the cost. These guys actually helped Bryston develop theirs. Oh, BTW I have no affiliation to Auraliti.
