I live in an apartment and therefore find myself doing most of my movie watching and music listening through earphones. I was wondering should I bother upgrading to a Dolby Digital reciver? I know that I will not get the full range surround sound that I would get with a full speaker system, but would I be able to hear any noticable improvement in sound clarity over the regular down conversion if I used earphones with a DD reciver? You see, the biggest problem I have with listening to DVD's through earphones is the sound is very muted in the 2 channel down conversion. When I listen to old 2 channel LD's the sound is often far more clear and robust that the down converted 5.1 on same film. Will listing to the fully decoded 5.1 soundtrack sound any better through earphones?
