Good day, fellas. Lately the upgrade worm is twitching again inside my brains. Now I'm drooling like a zombie over the possibility of upgrading my HD595 into something else.
The problem is: I'm on a budget! I'm planning on selling my HD595 to cover part of my new purchase, so I don't want to upgrade my D4 Mamba yet.
Long story short, I need recs on a low impedance headphone, which can be properly "pushed" by the D4, better than the HD595. I'm looking for good/great sound stage, and a little bit more of bass is a plus. I listen mostly to rock, some metal and some jazz.
