Hifiman is making amazing work with most of their headphones now! It would be so great if they would eventually make something even better than Orpheus! ...and price it less than LCD-3...so many people around the world could enjoy the best sound ever! Best of luck Hifiman:)
These headphones already exist, they're called PS1000
What's so special about them? Excluding the fact that they are... well... Grado.
They're special because they can also be used as dumbells
