Has anyone found a stereo Bluetooth receiver with a standalone board for the second channel? The idea is to be able to operate a pair of stereophonic loudspeakers free of any wires between both channels. The usual means of accomplishing the connection with the second channel (be it left or right) is via wireless internet protocol, DSS, or others between the main Bluetooth receiver and its standalone slave.
It has been used in pro audio for some time. I thought that, maybe, there might be something available on the DIY market by now.
