The XB1000 has deep bass, and has comparatively good clarity as far as basshead cans go. You're not going to get a lot of excitement out of it un-amped. It needs to be paired with a good bass boost amp to really shine, though.
Like the others have said, just wait around and see what the new cans have to offer.
Well I have a fiio e6. I might get a digizoid ZO 2 or an E11 but I'm not planning on anytime soon.
