Hi! Recently bought a Denon 2803. Very happy with the sound, but a question: is there ANY benefit to connecting my TV/DVD to the video-in sockets on the back of this amp. (Or to the back of ANY amp, come to that?!?) It just seems to add to the tangle of spaghetti dangling around the machine, yet I must assume there is some reason for the plethora of connections on the Denon.
