Isn't it basically what "DRC" does? (Digital Room Correction)

https://en.wikipedia.org/wiki/Digital_room_correction

I don't remember the exact order but way, way, way before the $10 K USD digital audio cable snake oil, audiophiles are going to say that DRC is the second single biggest thing that can enhance the quality of your setup (the first one being which speakers you're using and how you place them). Then source quality/amp/dac. And only way further down the line, for those who believe in voodoo, $10 K digital audio cables.

An objectivist audiophile would say that room correction is among the three or four grossly consequential parts of the audio chain. They are, in serial order:

0. Source material

1. Room correction DSP

2. Speakers (including subwoofers and crossover configuration)

3. Room acoustics (including positioning of speakers and listeners)

4. The human (ears, experience, expectations, ego, etc.)

All of the above are more consequential than anything else, assuming the core components are not total garbage, underspecified or malfunctioning. This includes the DAC and amplification.

Of the above list, I would place room correction at the bottom. (That still places it well above many things subjectivist audiophiles obsess over!) It is the cherry on top of a great system, not the means to achieving greatness. And it lets you get away with some things (most notably, mismatched speakers) to a greater extent than otherwise. But despite the name it can’t fix most real acoustic problems.

It can also make a system sound worse if it’s not used properly.

Seems to be some kind of DRC.

$10K digital audio cables are never a good idea.

I remember I went to some audiophiles house once to demo some speakers, and his "hobby" seemed to have taken over the house and common sense. He had crazy expensive audio equipment and some of the thickest cables I have seen, with the cables all suspended on little bridges.

All this in a room which was basically a square brick construction with glass windows on 3 sides, no thought to any treatment. He didn't seem to understand that the room was effecting the sound more than any DAC, Amp, Cable, or any of the other voodoo that was going on. I couldn't properly demo the speakers because of a particular standing wave. I concluded he probably had a hearing problem, he concluded he needed to upgrade a cable.
