Gain Setting impact on AV processor DSP Quality?

I have a nad AV processor and recently began using the DSP and the results were quite remarkable.  After what appeared to be very minor changes to the overall curve, ie smoothing it out and getting rid of some jagged activity, the tonality and vibrance improved substantially.

I'm trying to understand what caused all this to happen. I know there's gain settings within the DSP which I really didn't fool with, I only changed the level adjustments for each of the speaker channels.  Possibly could gain adjustments within whatever happens inside the DSP have impacted the overall quality of what I'm listening to?

I don't have any way to adjust DSP on my pre-amplifier which is used for two channel listening and that sounds pretty good without DSP. Maybe DSP would impact my two channel listening.

But for now I'm just wondering why the Quality improved so much and whether the gain setting had anything to do with it. And how would adjustments occur within the DSP capability of the AV processor? The AV processor doesn't have separate gain Controls.

Awesome comment actually learned a few things. A lot more going on Beyond just comparing curves I guess. Although do the curves in themselves highlight these things in anyway. The timing between speakers which I guess is influenced by very precise measurements which I see in the settings Post DSP measurements and maybe this is very effective.  The Rockettes do a great job performing without phasing and just a few out of phase rockettes would really screw things up.

Your system definitely reflects isolationism. I take interest in your diffuser panel behind your system although mine is a TV screen so it wouldn’t work for me. The cylindrical bass traps in the corner are cool, not sure I understand the sound reducer panels which I’ve never seen before and curious to know what they bring to the picture. The white rug is awfully scary.

Thanks for the info

Thank you for another awesome response.

Are you equating gain with volume?  

I always view gain and volume separate but many people tend to say gain when they mean volume.

So what you mean is volume is changed when the amplitude changes.

I always thought gain was different from volume. It's more of a voltage change to the signal which leads to distortion if you increase it too much.

Lots of people confuse gain and volume, it's really not the same thing. But then what do I know I'm just a dumb CPA.
