And I think I should disable it. It feels like it destroys a lot from the low frequency resolution, like there is no any detail in the low range.
I checked the calibrated results with an XTZ Pro microphone, and it showed EQ=Off to be too bass-heavy and EQ=Flat to be much more flat, but I can't believe that bass should be like this.
My best guess is that the algorithms compensate for the correct sound pressure levels and room acoustic problems but the DSP does too much rounding/truncating and destroys the fine details on the road.
I wonder if a dedicated sub and/or some physical room treatment would make the Audyssey result better or I should go for an Onkyo 818 with a more powerful DSP anyway in case I want to use Audyssey at all.
But either of these will probably have to wait (money reasons I didn't see when I started shopping AVR+speakers), so I would be glad to hear any other suggestions I might missed.
