I got a Pioneer 563a and have been using it for a month now. I thinking of getting new cables. right now i'm using 1 AR digital cable, 1 AR video cable and 2 sets of throwaway cables for the other 4 channels, I know not only are they very low end cables they also don't match at all. (the AR is the lowest lines they make). I think even the skeptics would agree that a cable ugrade is needed even for my lower end reciver setup (harman Kardon 525) But I'm looking at the options and anything decent from blue jeans cables or other places is at least half the cost of the SACD player, Do you think that it would be worth it to upgrade? Would there be benifits for even my system?
