I want one for two uses...

First and foremost would be to hook up to my home entertainment system.. My system only has optical connectors (but that cuz I have a Sony - I am probably in the minority here). I don't like the sound quality of the empeg's 1V outputs and this should fix it. Simply 2-channel stereo.

The second use would be so I could run a digital amp one day. This would be an expensive amp to get but it would help with noise getting in through RCA's. I also don't know how it could be dockable....

The first reason I listed would be enough for me to buy a kit/unit. The second would be enough for me to spend more, but it is not critical (in my situation.)
