Okay 5, the F-85 has only an optical digital output. So far as interconnecting cables(besides speaker wire)go, you may wind up buying as many as ten, but you don't have to immediately buy any. You got a composite video cable(yellow)and stereo analog audio cables(red and white)with the F-85. So you can connect one to your TV and two to your 525 to have a basic picture and stereo sound.
From someplace such as Parts Express you can get an optical cable for digital sound(under$10)and a three cable component video connection for a better picture. If you're going to play multi-channel music on DVD-As at some time, you can get six analog cables for that at least theoretically higher resolution connection between the F-85 and the 525.
