Oh yeah, the D7000 is definitely grand. I had it for about week until I realized I couldn't afford it just yet. The D5000 is alright, but I can't accept the price difference from the D2000, therefore that didn't make my list very well...although it was very addicting, I just couldn't justify the price difference. However, justifying the price difference from the D2000 to the D7000, no questions asked, it was definitely a yes.
I had thoughts, countless thoughts from night to night to go back to the D2000 instead of getting the SRH840 and trying it out (something for the budget), then after, I decided to take a chance and go with the 840; from there, I realized that even though the bass isn't as dominating as it is in the D2000 (and I use that term loosely because the bass is phenomenal on the 840s), the detail and instrument separation are just way superior than the D2000 (very close to the D7000's), the bass is very tight and balanced (it doesn't rule over instruments or show off how directing it is), the sound is crisp and dazzling for very easy listening sessions, and overall the headphone is just very versatile and very sensitive as many reviewers referred to it as...I honestly can hear every little thing in recordings...from the littlest things (even the artist breathing) to the biggest. After all, it is a professional studio monitoring headphone, so that explains why it's very sensitive and resourceful...just got to get those recordings confirmed, established.
