Well, circa September 2010, it DOES just that below -0dbs and it is of course annoying. Overall bass bloat seems to also be a common complaint that is also readily dismissed by the quasi-experts on the Aud thread who will simply explain that you do not understand a myriad of factors/goals of the technology.
Ok, then.
The very purpose of it is debatable to begin with IMO. You generally have the volume DOWN significantly to not disturb others or because those watching do not particularly enjoy more "full-bodied" volume levels, no? I'm sure that's wrong, lol.
So, what does DYN EQ do? It BOOSTS the most bothersome (to those on the opposite side of your walls) freqs (lower end), so sure it may sound "better" to you at lower volumes, but ask your neighbors, spouse, roommates in opposing rooms what THEY think, lol. And you may say you don't care, but if that's the case why lower the volume to begin with?
Doesn't make a lot sense to me.
Ditto for Dyn Vol. The idea of it is fine, but last time I checked, most of us spend all of our money of this to crap expressedly to HEAR the dynamics of the audio, and while I understand loud commercials are undesireable, you pretty much are choosing one of two evils here: loss of program dynamics, or loud commercials/troublesome night-time dynamics.
Simple as that. Since both are defeatable I don't really lose much sleep over them.
MultEQ XT of course is phenomenal.
So:
MultEQ XT: 9.5/10
Dyn EQ: 5/10
Dyn Vol: 4/10
I know this will pull the audyssey apologists out of the woodwork, but, whatever.
