I've now updated the design with USB audio and whip antennas for a little better range. I realized that the radios in these are really only Bluetooth class 3 devices, so range is limited to 30 feet or so. Still, it's cool to be able to plug these into USB and stream anything playing on your PC to a high quality stereo with no loss of quality and one cable for power and signal. The 44.1 kHz sampling rate restriction remains, but I'm working on that.

Anyone interested once the last of the bugs get worked out?
