Caution about the long interconnects suggestion by Jimbo...
Long runs of RCA can cause problems. RCA is not optimized to run long lengths and at those distances can start acting as a big antenna. Speaker cables do this also, but the noise levels inducted are rarely a problem (though they can be audible and smear small details).
This noise CAN cause problems with a power amp. Amplifiers, particularly wide bandwidth designs, amplify everything fed into it...good or bad. In the worse case, the noise can cause instability in the amp (this happened to a customer of mine with a Threshold...he blew the amp). This is why balanced connectors are the de-facto standard in pro...they reject noise. Also at 50 feet, the capacitance of the cable can become a problem and you can end up with a badly rolled off high frequency if you use the wrong cable or your preamp isn't capable of driving long lengths (many aren't).
Also, if you are to run the speaker cables in the wall, make ABSOLUTELY sure they are CL-3 rated for insurance purposes! I can't stress this enough!
I've had good luck with the Wireworld speaker cables over long runs. Their symmetrical coax design rejects noise very well and they are CL-3 rated.
