Connect a Denon AVR-X4000 pre-amp output to "unknown" converter, and then play sound across the LAN to an Airport Express W/speakers?
I have an Airport Express wired to a couple nice Bose speakers. I have it setup so that it acts as a bridge, so it wirelessly connects to my TimeCaptule from anywhere on my LAN where I have a good signal. Now I would like to purchase a Denon AVR-X4000 AVR receiver. I would like to wire some kind of adaptor from the pre-amp output to something that could connect wirelessly to the Airport Express. Does anyone have a recommendation on such a device? It would have to be some kind of converter from a pre-amp input to a wired or wireless network. I have a switch nearby where I would plug in the Denon AVR receiver, where I have plenty of ports available.
