I have a few questions about my Denon 3803's sound processing options. Currently I only have two front tower speakers. On many DVDs there is the option of DTS 5.1 and Stereo. To my ears, the DTS sounds cleaner with a higher SQ. The stereo seems to sound more full, picking up bass that the DTS mix doesn't seem to have. Can anyone explain to me what my receiver is doing to the sound when it knows I only have the 2 front speakers? Which mode should I be in to make things sound the best? I am mainly interested in music and concert DVDs. This, along with a lack of $$, is why I've only got 2 speakers right now. Thanks in advance for any help and education you could provide me!
