Is there a way to use the power of the RX Z9 to drive the CX A5000 preamp? In theory, it should; I already own an RX Z9, which is a beast but without the HDMI and some of the newer features on today's amps, I feel as if I'm missing out on some things. I want to keep all my speaker connection on the Z9 and the use the CX A5000 as the preamp to support all of my HD and other audio video devices. According to the Z9's owner manual, there are several option for connecting an external preamp ( the FRONT IN/ CENTER IN jacks) or (the MULTI Ch INPUT jacks). My question is can it work and what would I be missing if anything in this jerry-rigged setup.
