So I decided to keep my D7000 and possibly sell the HD 800... (really hoping to keep both but my girlfriend and family do need xmas gifts.... *sigh*)
They are simply too musical, and too good. Electronic music sounds sublime, and less busy pieces, regardless of genre, always sound right and relaxing via the D7000.
It is a shame that these headphones seem to be the first flagship most people get due to their lower price, and the second people get a taste of real high end headphones, they sell their D7000 to move on to "bigger" and "better" things. These should not be viewed as "tide me over" headphones or "I couldn't afford a real flagship"headphones. That is unfair an inaccurate. They are world-class headphones in every sense of the word.
Now, my LCD-2 certainly ARE a better headphone technically speaking than the D7000 and I find their balance perfect... they sound like life and are ruthlessly revealing. All great things and obviously IMO, to my ears, etc etc. The LCD-2 are perfect, and technical/sonic marvels - save their weight.
BUT the D7000 sound to me like what I though of music in my childhood... what a really good movie theater sounds like... what a club might sound like if they had good amps and good speakers... a good rock venue... they just sound like music... yes they are coloured, but most gear is... and the colouration is what makes them such a "comfy" and "seductive" headphone.
That being said I want to stress again they really are not inferior like most people seem to think these days. They have their issues, but most headphones do (I would say all but someone is going to disagree). The HD 800 to these ears does not have magically better drivers that are "on a different" level... it just had the opposite problem of being too bright, and a little "overly dampened" while the D7000 need to be dampened just a tad more. It is just the polar opposite but they are both very close in terms of actual SQ. The LCD-2 is above both... but I hope this puts the D7000 into perspective for some people. It is not a second grade flagship... it is a flagship like any other and it sounds damned good.
With proper amping: Like my balanced phoenix with 0 negative feedback and a kickass source like my Ref - 7 they are super revealing and the detail is great. They are handicapped by their closed nature int his respect, especially depending on the volume but this is also what makes them sound the way they do: damned good.
So like Gui Sensei and a few others, the magic is not in the most correct headphones technically speaking. It is in the most correct sounding to your preferences or music. This headphone is not hi-fi as it is not always highly faithful, but it is highly musical and always sounds good if the volume level is in good taste.
So for those who avoid these like the plague due to "boomy uncontrolled bass" : Get a good amp, listen at reasonable levels, and MAN UP!! That being said I do not think these headphones do "crowded" or "busy" music that well like thrash metal for an example but most things are an absolute joy.
The D7000 are exceedingly comfortable both sonically and physically, although I do find the HD 800 "disappear" tactic impressive and I adored that, the D7000 are close in comfort. The LCD-2 are very comfy although the least of the three... but they are SOOOO heavy.
What sealed the deal for me today, why I could absolutely NOT sell these headphones, was after an hour listening session of Armin Van Buuren, Excision, and Kings of Leon... I realized nothing sounded remotely bad... hell it sounded AMAZING...they all sounded so "comfy", so "inviting" and "seductive" that I knew I could not let these go. If one will be going it will be the HD 800. while the soundstage is to die for as well as the ergonomics... it really is not that much of a technical marvel... and damned expensive. But it is extremely enjoyable but my funds are running out really quick and I am most likely going to have to choose one. Being unable to work for the next month due to my operation has made monetary matters even worse... but I am in no real danger even if my hi-fi spending is cut off... I am a student living at home after all haha.
/end rant (forgive me if I sound insane, I had an operation last Wednesday and am on heavy narcotics)
