I'm been having discussions with different people about the hook up of dvd players with regards to the audio set up. Some people say that you should use the optical cable for the sound and some say use only analog cable (jacks for SACD)I am using a Marantz DV9600 dvd player, which has an awesome audio processor, and a Marantz SR8500 A/V receiver which is just as great. Plus I have straight wire cable used for all of my outputs and a M series high performance optical cable. I was told that if you use the analog outputs, you are using the processor in the player and if you use the optical, you use the processor in the receiver. With the processor being as good as it is in the player, I'm not sure if should use only that. Both sound good, but I want the best sound to come out when I watch a movie. If anyone can shed some light on the subject please do. I'm up to try everything.
