Just took delivery of my brand new Denon 3800. I haven't hooked it up yet since I'll be moving in about four days, but I did look at the manual. There seems to be an enormous amount of control over picture and audio settings. Hue, Contrast, Delay, etc. What I'm wondering is if I should adjust things on the DVD player side or should I adjust these things on my preamp(Anthem AV20)? Could someone run down how they've got their player setup?
