Direct Mode for Denon-988....advice from any Denon owner please

[liquidice]

I have been messing with this receiver since I bought it 3 months ago. To put quite simply, based on what I read in the manual, it would appear that Direct Mode would be the next best thing to Pure Direct mode as far as audio quality. "Great!!!"...I thought, until I play music or movie with it set in Direct Mode, then realize there is very little bass. Why is that?...am I messing with something I really don't need to worry about? For the best sound, it is set on Standard, but the fact that Direct is still just sitting there unused makes me feel like I'm neglecting a child! Denon is ZERO help with this question. Called them numerous times, each time a different answer. This should apply to any Denon users, so I'd love to know what setting you use most, and for what your using it for. Thanks.
