My sub cable gave it up(long story involving kittens), should I replace it with another expensive monster cable or will cheap rca's work as good? I have a denon 3802 I bought it when it was a 2000.00 dollar reciever and would like to have the best quality sound out of it I can but 70.00 cable vs 15.00 rca's, is it really worth it?:confused:
