I'm of the opinion that it does a good job at its primary mission.
At my home and on my equipment dynEQ OFF sounds better than it ON to my ears at least...i know the + and - of it but i am more keen on keeping it off as i really dislike the boost (especially of surrounds)...but if i would have to listen at -25 below reference then i think it would make sense...to each his own i guess

Do not let overanalyzing have you miss out on the benefits of DynEQ.

Your comments about the bass control show that it only impacts the front left and right channels and nothing else. This is typical of many receivers.

Great stuff, Alan! Thanks for taking the trouble to post all of this. I have a question, and then some comments. First, were you measuring with Audyssey Flat, or Audyssey Reference? The graph you showed, with no DEQ, looked like the Reference Curve to me. I wonder if Audyssey Flat would show the same boosts in exactly the same way?

Looking at the bass boost at -15 MV, it looked to me as if there was about a 9db increase at the lowest frequency. If so, wow! Am I reading that correctly? That is much more than what Jerry measured several years ago (in the RLO section of the FAQ), and I am trying to understand what variables might account for the difference. Of course, I may just be misinterpreting one of the graphs in question.

I know it's reassuring to learn that you aren't crazy, but remember we only have the measured treble boost as empirical proof of that, so it's too soon to reach definitive conclusions based on a single indicator. I don't think I am hearing much at, or above, 13K anymore, so unless the volume were pretty loud, I am not sure how aware I would be of the 3db treble boost at 13Khz. It does seem to slope up gradually. If you can hear that in movies, that's pretty cool. I absolutely hear very subtle differences in music, but not nearly as much so with movies, which is where I am sometimes using DEQ.

With respect to the tone controls, they are unfortunately limited just to the front speakers. Gary and I have discussed our wish to have more user control there, as well. My theory for why most AVR's only implement tone controls for the front two channels, is that every system consists of at least two channels, and some people like yourself, only listen to music in stereo, regardless of how many channels they have for HT. Oh well!

FWIW, I don't really think that measurements demonstrate that we "should" or "shouldn't" like something, which is not something that you were saying, anyway. I don't believe that our preferences need substantiation, or vindication. They just are our preferences. But I love the analytical aspect of this hobby too, and like trying to understand the what and why of some of this. Among other things, I think it really helps to better understand our available options. So, thanks again!

Happy Thanksgiving, everybody!
