I just got my HD700 in the mail and I don't understand all the hate on these. Sure they are overpriced at $1,000, but for $550 they are incredible. These aren't all the bright to me ears. If anything they are pretty smooth, but the treble spike does show up on some of my stuff (Children of Bodem, Lonely Island). Their soundstage is bigger than my HD600, but not by a lot.
They are a big step up over my HD600, DT990, X2, and K7XX, but they do not want to make em sell my other phones. They all have their strengths/weaknesses, and I enjoy them all. Are they on par with my T1?No but are close to being on par. These are pretty versatile but I do feel that slight treble spike can be an issue for some people, but to me it's not that noticeable.
More later once I get more listening in. Right now I am driving them on my Auditor, and they sound superb and the Auditor drives them with incredible authority.
