Wifi Receiver Is There A Ethernet Or Wifi Home Stereo Receiver?

Is there a ethernet or wifi home stereo receiver? - wifi receiver

Suppose you want to use Windows Media Play to another computer via my wireless network to play. Is there a stereo or surround sound, connect with me in connection to the Ethernet port of my router or Wi-Fi and receive audio from any of the Wi-Fi will be transferred many of its facilities?

I do not want an add-on that I use a HI-Fi existing design. I want to be the chaos added to the stereo.

Thank you!
