YES, YES, YES...
i too, am a believer. using the optical/digital cable from the dvd/cd to the receiver has greatly increased my quality of sound.. in fact, without the dig/opt cable, you wont get the 'true' digital signal that is required for DTS and dolby digital movies.
i have a buddy who is linked with the standard rca cables, he he couldnt figure out why his receiver wouldnt go to the DTS option.. i had to tell him it was because it isnt receiving a digital signal.. he went and got a dig/opt cable, and has been good to go ever since.
