I'm thinking about a new pair of phones. Let me start off with that I have a pair of Ultrasone HFI-780's that I am pretty happy with, though I'd like to upgrade from them. I really do like these phones and I am hesitant to buy anything else because I'm not sure the money is worth the reward. I'd like to get a phone with a better soundstage. I also own a pair of ATH AD700's... I know for closed cans, the 780's arent bad... but the soundstage of the AD700's is a whole nother world. The AD700's are weak in the low end though. I also prefer a closed back design to cancel out noise/not annoy others.
