Thank you for mentioning AutoEQ, I didn't know about it and it looks like a great resource :)

I wonder why laptops don't come with an internal speaker DSP profile loaded onto the EEPROM. This seems like one of those things that you really just want to do in firmware.

IEMs and headphones come EQed out of the factory AFAIK, but apparently quite poorly. I ran the autoEQ profile on my Moondrop Aria beater IEMs and it both cut through the muddiness and opened up the soundstage quite dramatically.
