Audiophiles will tell you that unless the source material was mastered in 5.1, a surround sound system can actually make things worse as a general-purpose sound processing algorithm that tries to take a 2-channel source and make it sound like it's coming from 5 distinct directions can't make better decisions than a sound engineer.

This is like people who think an upconverting Blu-ray player will make their DVDs look better because it outputs at higher resolution, without realizing that the extra information is simply not there to begin with. You can resize an image and then apply edge detection algorithms to it to increase its sharpness all you want - it's not going to "look better" by any measurable means.

That said, perception is subjective--if you try different settings and to you something sounds better than the original, than by all means, use that, enjoy, and forget what everybody else is telling you.
