I think those days of chasing after the sound is over for me - after many years of doing that.
I do agree it is all about the bass EQ, not about flatlining the FR. Some like flat, some like more. It’s about the sound we love, not how flat it looks on REW.
With DM, I know how much I absolutely love Audyssey Bypass L/R + DEQ and +5dB Trims for all speakers.
With Yamaha, I absolutely love Manual PEQ +3dB from 40-100Hz.
As you say, after we’ve found our magic sound, there’s no point wasting any money chasing after some other EQ just because someone says it’s great for them.
Been there, done that several hundred thousand dollars ago.
These days it’s all about finding more great movies and TV shows.
