I've got plenty of great active speakers that I would like to connect to my sound sources wirelessly. HD Control Center (without speakers) seems like a nice solution. However, I do need a WiSA receiver and DAC for each speaker. But these are not easy to come by. Found only one: http://www.summitwireless.com/summit-pro-audio-rx.html, which is actually just an eval platform. My questions are: Will the HD Control Center work with any other WiSA receiver? What receivers are available?
