Disclaimer:   1. This is an Aune B1 Canadian tour unit. The tour was organized by hakushondaimao, and many thanks for his efforts. I had the B1 for a week and as the last tour member I sent it back to hakushondaimao. This review is not a required precondition of tour participation.   2. I'm in no way associated with Aune.   3. I don't believe in burn-in. I almost always use stock cable or the cheapest one I can find and call it a day. I don't believe I can distinguish lossless formats from 320kbps mp3 in a blind test regardless of any gear...
