From what I've read, both YPAO Volume + Adaptive Dynamic Range Control are more similar to Audyssey Dynamic VOLUME
and Dolby Volume + Leveler aimed for
LATE NIGHT WATCHING, not to
Audyssey Dynamic EQ.
Audyssey Dynamic EQ is NOT for Late Night Watching!!!!
Audyssey Dynamic EQ will mainly BOOST the mid-bass and slightly boost the upper treble.
I use Audyssey Dynamic EQ 100% of the time, whether the volume is 70dB or 100dB.
I use Audyssey Dynamic Volume 0% of the time.
I know PENG posted graphs of Audyssey Dynamic EQ.
Has anyone seen graphs of YPAO Adaptive Dynamic Range Control?
I've never used Yamaha.
I have tried the Anthem ARC Dolby Volume & Leveler feature at a friend's house.
I found that the Anthem Dolby Volume & Leveler are more like the Audyssey Dynamic VOLUME, and nothing like the Audyssey Dynamic EQ. I didn't feel that the BASS was changed at all.
With Audyssey Dynamic EQ, I find that the BASS is changed significantly by becoming more Dynamic/robust. I didn't feel that the treble changed at all audibly.
I caution using high volume with Audyssey Dynamic EQ when watching certain movie scenes from movies like "Interstellar" and the opening scene from "Edge of Tomorrow"!!! You will literally jump off your seat and be acutely petrified.
It seems to be Dolby Volume + Leveler and YPAO Volume + DRC
compresses/reduce the dynamic range and ultimately
REDUCE the volume if it gets too high.
Audyssey Dynamic EQ is just the OPPOSITE in my experience - it
INCREASES the Dynamic Range and VOLUME.
