Hi, I just bought a Pioneer 563A DvD player and a Yamaha HTR-5650 receiver. I don't have anything set up yet because i'm moving in 9 days and i'm also waiting for my 65 inch widescreen Toshiba to arrive at the new house The guys at the store sold me 3 pairs of AR master audio cables....but i think i just read somewhere that i need 4? Can someone confirm this? do i need 3 or 4 for my set up? I don't want to move into my place and start hooking up my system that night, and find out i need another set of audio cables and have to wait until the morning...i may go crazy! Not sure if it makes a difference but i will have a HD TV, HD digital box, my receiver, DvD player, x-box and gamecube. also what's the difference between using the audio cables and fiber optic. I always thought fiber optic was "the best for sound", but the guys at the store sold me on this 563A and they told me the best way is NOT to use fiber optic, but to use audio cables for sound. they told me its the "new" way to listen to DvD's and the best way. I'm only using my DvD player for DvD's....not much CD's.... Can someone explain in layman terms the difference and if the people at the store are correct. Thanks a ton Thanks for sitting through my first post here.
