How can it be more technical, if it is brighter overall?If you like Mext, then try Mest, its a direct upgrade from Mext. And at the time I was in hard decision to sell M9 or not (because I just bought Mest that time), since I also have M7, so I decided to let go the M9 even though sometimes I still miss them but Mest is great in different direction from M9 (brighter overall, but more technical)
As an musician, i am always confused about how audiophiles use these terms^^
