Equalizer in a Hi Fi system

Does anyone know the answer to my question?

My room embedded mechanical equalizer grid is made of Helmholtz resonators and Helmholtz diffusers, they modify the pressure zone grid of the room by their location.

No DSP analog or digital can do this...

Listener envelopment (LV) ask for more than single frequencies response modifications from the gear ... It ask for the room pressure zone modification and adress speakers/room coupling...

Acoustics rules not the gear...

it is not practical for living room and wife. But i cannot change acoustics truth because of my wife convenience... 😁😊😎😋

“I take it they're mostly digital by now for a number of reasons, though analog mixers are no doubt easier/more intuitive to use. ”

maybe in mixing. In mastering (most similar to our use case) analog is still felt to be superior. Although the gap is closing. Read threads on Gearspace if you want to educate yourself on what goes on in the studio. As opposed to making assumptions. 

@mahgister , your ‘natural’ method, while impractical and unsightly to wives, is certainly fascinating. I have no doubts you are maximizing sonic returns on the gear you have. 

Yes. I mention it for information only and for those who have an audio dedicated room only for experiments..

 A single straws change S.Q. in my experiments .. 😊

My wife will divorce if i tried these set of experiments in a living room and she loved me ..

 I use with success three analog EQ. for sure  but basic one unlike yours  though very well implemented for my needs ..
