I used to believe EQ was this magic method to dramatically improve sound quality. I would always use the Audyssey on my Denon x4400h the moment I do anything to a system.
That is until I upgraded my speakers to the Sierra-2EX V2. Based on Dave's advice to limit EQ only to a room's transition frequency (i.e. < 300 hz), I found out the speakers sound so much smoother and cleaner without most of the EQ. To me ears, there was like an edge or harshness to the sound with the EQ running full frequency.
Without the EQ above 300 hz, the sound is just so much cleaner and "pure" as if the performer was there playing in the room. I'm not sure the reason for this but I'm curious why.
With this experience, I think there's way to much hype with the different EQ types such as Dirac, Ymao (or whatever that is), etc. going around now but I guess to each their own. IMO, all you need is below 300 hz and that's it.
