Yeah man, I really love having to pick up a computer for going into my streamer's configuration in order to mess with eq curves every time before listening to music.
And then still get a different sound than I would from the headphone I'd be trying to emulate anyway.
This is one of those hilarious moments that happen ever-so-often here where someone ignorant comes along and asks something to the tune "I want THE BEST headphones, no limits budget!!!" and immediately to a 180 when they get pointed at the ab1266 or the he1.
I have the hottest of takes: Different people like different things.
Shocking, I know.
If you want to know whether you'll like a headphone or not, go to an audio store and listen to it.
Diminishing returns don't exist because "better" isn't quantifiable: wtf is "5% better" or "80% better" of something that doesn't have a quantity associated with it?
