Someone told me of a wireless system where I can hook it up to my Line Out on my sound card and send my mp3 playlist to my home stereo. Anyone heard of this? If not, I'm sure I could just run a line out of my sound card into my receiver...however, my receiver is on the other side of the house. Do I need to put anything in between the sound card and the receiver? Does the signal deteriorate over long distances? Help.
