One end hooks up to the puter via USB cable. The other end to your Integrated or receiver via an open input with a mini jack to dual RCA cable. For example aux 1. Sounds like the range would handle your situation to your upstairs room. The few reviews I read were positive. I have no first hand experience with this unit.
Thanks Ken for posting this. It has definitely peaked my curiosity. I have been wishing I could get my pandora stations streaming to my main system. This might be the answer.
