From personal experience the only advantage I've ever seen aside from build quality (but even then, you can't upgrade most of them unless you have a mac pro) is the fact they run more reliably without errors on Avid software.
What headphones are you all using? And why did purchase them?
I personally use Sennheiser HD280's. I initially bought them because of the overwhelming amount of great reviews it had, and never really felt the need to purchase a different pair.
My guess is gearslutz would tell you one of two things.
A. Get a pair of LSR 305s or equator D5s.
C. Don't bother because you don't have any treatment (lol)
