Okay so My home theater consists of an Onkyo HTIB (not for long though) with a Samsung LN52a650. My Onkyo receiver is slightly outdated and doesn't have any hdmi inputs. Now the way I had it set up for quite some time was hdmi from satellite to TV and then a digital optical from the satellite reveiver to the Onkyo receiver. Well out of boredom, instead of running the optical from the satellite to the receiver, I pulled the optical out of the satellite altogether and ran it directly from the TV digital out to the Onkyo receiver and wtf, it make a helluva difference in sound quality. It was not only clearer, it was a helluva lot louder at high volume. Can anyone answer why this is? I am assuming it has something to do with the hdmi cable but I don't understand why it made such a noticeable difference?
