I have the ENO AG to demo as a dealer, I will post my opinions as an audio guy after I have spent some time with it. My room will finally be going back together now that I have a 271 again. I have kept the new factory 8kse in the boxes until the room was back together. It has been killing me not to open them. For USB there is also the Audioquest Jitterbug.
