M50's have 45mm drivers, and the LP's are known as loose basshead cans, so you can't exactly say they "pull it off."
If they fixed the problem that Val quoted there, I'm glad. If not - then I'll be looking at the new Denon line or the PSB's. No offense to V-MODA; they do great work here on the forums, and their headphones sound great, but this one won't work for me as well as I hoped if I have to buy a portable amp to carry around, just to make them shine. They'd end up costing more than what I thought they would.
