I know that this is a terribly convoluted question. My ultimate goal is to listen to MP3 music from my basement computer to my receiver upstairs. I know that there is a wireless RCA RD900W that would accomplish that, but I have some pre-wiring that i was wondering if i could utilize. Here is the set-up... - Receiver in the basement (hooked up to HT) - PC in the basement (within 15 feet of receiver) - Second receiver in the 1st level. - Wireless Speakers used to listen to music from the receiver on the 1st level - Speaker wiring in the walls directly from the receiver in the basement to the receiver in the 1st level. This wiring is long enough to extend to the computer, but I am not sure what good that will do me. To me the optimal solution would be to use the existing wiring between my PC and the receiver upstairs and continue using the wireless speakers as currently set up. Any ideas?
