I didn't mean bluetooth, I was referring to wifi/dlna (maybe Heos, haven't used that). As long as the avr is connected to your network it's fairly simple. You're afraid of losing data? Not an experience I've had streaming my own content over my network; we can stream video without issue, audio isn't even close to that. Plus you can demo another feature....
You can hardwire in a variety of ways, tho, like your plan with the Audiocrap device.
