i'm home from college for a bit and just picked up some D7k's. my mother was, for some odd reason, very upset to find that i'd spent the majority of the money i'd made working this past year on a pair of headphones, but i forced her to sit down and put them on. after close to 20 minutes of me shuffling through FLACs of songs she knows and loves (michael jackson, aerosmith, etc...) she was literally dancing in her chair with a huge grin on her face. she then took them off finally and said, "i can't believe how much stuff i'm hearing that i'd never heard before... it doesn't make me want to spend that much on headphones, but i absolutely understand why you did."
at any rate, i'm absolutely floored. well, i actually have to say that i wasn't surprised at all by them; when i first put them on i just smiled huge and began typing up the ebay auctions for my pro 900s and 990/600s as music pumped through the d7k's. from the research i did, in this thread an others, i'd basically concluded that the d7k's would take 95% of the bass slam and extension from the pro 900s, and have 95% of the soundstage and imaging capabilities of the 990's have, as well as having the more natural, detailed sound of the 990's. the d7k's do all of this and more. the combination of explosive bass, incredible detail in the treble, and unparalleled imaging (for a closed can especially) make them an absolutely awesome all-arounder. EDM still sounds just as good on the low end as the pro 900's, but there's so much more now in the other frequency ranges. and, if i want to listen to some rock or watch some tv or even game competitively... the D7k's stay on my head! truly, a phenomenal can in all regards.
