My RX-A780 was setup as 5.1.2 in my living room and was powering my kitchen stereo speaker pair by direct wiring. Using Musiccast I included my Yamaha Musiccast 20 in my bedroom. I was going to upgrade to the RXA6A in 3 years when 8k will be more available, but I got an unbelievable price on one, so I bought it.
