Thank you for the reply. To your inquiry Why Bluetooth? Yes, I understand that the audio quality may not be as good, but then, at my advanced years(over 70), neither is my hearing ability. I am putting together two separate systems, one for family use, the other for my studio. The Yamaha rcvr has outputs in optical, Coax, 3.5mm, and RCA R&L. For sources, I have a DAT tape deck, turntable, and a CD player in addition to to the FM radio of the receiver. Changing over to Bluetooth will enable me to sell or simply jettison a mixed bag of components acquired over 50 years. In the studio, to respond to one inquiry, I built the wired stereo speaker wiring behind hinged crown molding, so if I'm not happy with BT, I can revert to the original wired system.
