1000+ Head-Fier
Instead of an open headphone and/or re-hashing more T50RP driver usage, I'd prefer a new design, new drivers, etc... (I basically think we have heard the limit of those Fostex drivers and anything else that might be squeezed will be minimal).
So come on Dan!
I think that this is very interesting, but in a different thread. Seems like finding a driver that is an improvement over the T50RP driver is the most important part of the equation, as the 3D printing for the cup appears to give Dan a lot of flexibility in the cup design.
