Michael, I'm confused...your saying you can't reach the knobs?

If you have the sub at 9 o'clock I would think your Sub level setting in the Denon would be like -10 dB's to compensate for having the sub gain so high to achieve 75dB's approx. on the meter, +5 seems way to high. If I even put it on 8 o'clock my denon is on like -5dB's to achieve 75dB's from the main position.
