I am very surprised Headphone.com described the D2000 as being neutral and flat, they couldn't be more wrong. These would be terrible for studio use. I'd be very surprised if any studio has a D2000 for use anything other than taking a break for pleasure listening.
Studios use headphones designed for studio use. These are flat, neutral headphones that are designed for durability. K240, DT48, HD25, SRH840, V6 are just to name a few. Sennheiser, AKG, Shure, Beyerdynamics and Audio Technica have all made a name for themselves among professionals. Dennon definitely has not. Denon targets the audiophile market which is sometimes the opposite of professional grade gear. Professional grade gear is not about getting pros to fork over the most money over for brand name, and other gimmicks. Compare the HD25 which is used in the studio vs the HD800 by Sennheiser which is targeted at audiophiles. Same for Beyerdynamics, their DT48 is for Studio, the T1 is for audiophiles. Very different headphones. AKG is pretty much a pro audio company, they didn't make $1,400 audiophile headphones, their best headphone is the Q701 which is arguably among the best headphones for studio use.
Put it this way, some professionals think audiophiles are morons. And personally in general I trust a professionals opinion who bases their opinion on facts, science and engineering than any audiophile here on Head-Fi who seems to be more affected by price, rarity, and exclusivity of an item. Professionals are much more pragmatic about the gear they use, they look for something that is functional and gets the job done.
Head-Fi is not the best forum if you are looking for professional gear and looking for an opinion on various headphones for mixing. There are some professionals, but the vast majority are not, and most of the Head-Fiers who promote cables, Grados etc are not professionals. Just google gearslutz. That forum is dedicated to professionals who share their opinions of headphones for the right job. That forum also has industry leaders among professionals responding to questions as well.
