I do understand that Discrete has LFE set to -10dB and Cinema to 0 at default, but the 550's test tones and and DVD I try (DVD-E PAL and NTSC, and Avia) show that the bass channel is 10dB low on the meter with the levels set at 0. I searched before posting and it pulled up 4 answers from 2008 all of which referred to the 10dB difference in presets.

I've only watched one film so far which didn't sound bass heavy. It will be interesting to see what readings the same discs produce via the HD621. They produce expected results through the SP-DIF output.

Edit: The Ovation disc certainly does I didn't try DVD-Essentials through SP-DIF.
