I really should get a decal like this for my MBP. The Joker one is the one I've had my eye on for awhile.
I don't know. I picked the HD800 over the LCD 2.2 even though I listen to a lot of Bass Heavy EDM. I felt the HD800's bass just has more texture than the LCD 2 or HE-6. There was something about it.
I think, in my experience, the only thing the HE-6 significantly passes the HD-800 in is bass. The HD-800 sounds more open, has better separation, is more comfortable, and goes toe to toe in most other areas. The only reason I use the HE-6 over the HD-800s is when I want more bass. Bass aside, the HE-6s are a step above in most areas over the LCD-2.2s when amped properly, but I still prefer the LCD-2s because of the signature Audeze sound and oh, that sweet luscious bass. I just can't go without it... If bass was not something I was too concerned with, I'd go with the HD-800s and be done with it. No second guesses or doubts about it.
