Sigh, I need to remember to never read the YouTube comments on @Techmoan videos. There is *always* a huge misguided discussion about analog vs. digital that raises my blood pressure. Your argument is invalid unless you have ABX tests to back it. Hint: digital does.
That is a solvable problem. I have a DIY speaker controller, with 6 channels and 15 biquad EQ filters per channel (90 filters total) at 96kHz/24bit, plus a full matrix mixer. End-to-end latency is something like 30 samples (that's about 10cm in air).
