Thanks for the comparison, I figured it would be a huge jump. It's either those or a set of DT990 250 or 600 ohm I'm thinking. I just went down the amp path and got a Schiit Magni 2 Uber, which is also what's sort of driving the desire to upgrade now that I've got the power. I got a Mixamp Pro Tr for chat on my consoles and that seems ok but I may bite the bullet and just get the full stack and order a Modi Multibit for solo play.
I mostly use these to game with so soundstage is important, any thought's there?
