There’s a big difference between a $100 sound system and a $1000 sound system. I’ve gotten the “audiophiles are dumb” lecture for suggesting someone upgrade from 2x4" computer speakers to actual studio monitors for working on their music. But their speakers literally could not reproduce some of the frequencies thru were trying to make, so they mixed the bass WAY the fuck too loud.

But yeah, diminishing returns start to kick in around that point. Quickly becomes the eternal story of a Fool and His Money.
