Someone mentioned the Sonos Connect - initiially, I couldnt recall which component that was but a little research revealed that its the new name for the ZonePlayer 90. Wikipedia dont appear to have the memo either:
The ZP80 is an amp-less ZonePlayer that includes optical out, coaxial digital out, as well as analog RCA inputs and outputs. It has a built-in two-port Ethernet switch. The ZP90 is the successor to the ZonePlayer 80, upgraded to SonosNet 2.0.
I'd want to see the iOS app in action with the Connect, but the ZonePlayer box itself isn't as expensive as I had feared. Where this system gets seriously expensive is when you want to have sound in every room in your home.
