For DVD's you'll need a digital coax cable or an digital optical cable. For DVD-A and SACD, you'll need six, yep, six analog RCA cables. I wouldn't spend too much on the cables. Doesn't make any sense to spend more on the cables than you do the player. The days of analog cables are numbered anyway. Very soon you'll have one, maybe two cables coming out of your DVD player. One digital video and one digital audio.

btw...picked up the 563a at lunch today. I'll have it hooked up tomorrow.
