Just got mine and wow... Only able to run through my Dragonfly because I'm at the office but I'm pretty impressed with the HP. Visceral bass and great detail - definitely a different enjoyment from the HD800s!
If the th600 sounds just as good as the 900s, I'd def forgo the birch earcups to save some bones!! Can't wait to hear reviews on those as they get released..
