I did search but couldn't find a device, if it exists, that I'm looking for....

I am looking for a device that streams audio from my PC using I-Tunes/Windows Media Player to my stereo where the wireless device that interfaces with my stereo receiver only receives the audio stream but doesn't have any kind of built in functionality or communication back to the transmitter or PC. I had a media center that would stream audio from my PC to my stereo but it also ran their 3rd party app that would display on my TV to control what was being played, etc. I have a "back office" way of controlling my PC and don't want to run any 3rd party applications (aside from the driver for whatever the device is) and have no need or want of a streaming device that does anything but pass an audio stream and nothing else. I hope I was able to adequately describe what I'm after. Anyone know of such a device?

Thanks in advance,
Zak
