So from reading on head-fi and a couple other forums it seems that with JB 4.1 USB audio is supposed to be supported. The enables audio to be played thru an amp/DAC essentially unprocessed then to be converted by the external DAC. The talk is all about the S3 now, and understandably so since he's the new guy in town, but I want to know if this works or is even possible with the nexus. I don't want to run out and spend money on something I am not sure will work in the first place. I have been looking at a fiio e7.
