From what i have gathered the 2000's are more flat across the spectrum thus being better for monitoring work, either studio or live (more natural sounding) and the 5000's and up are more suited for audiophile hi-fi listening where the sound is richer and 'glorified' somewhat.
both beautiful headphones, just depends on your application..
2000 - natural, good replication of the artists (or shall i say mastering engineers) wanted sound and true representation at a FOH position.
5000 and up - more forgiving, improved bass response, richer sound
please, I may be wrong, just thought I would throw my ideas in, anyone else, agree ? disagree?
thank you.
p.s. sorry if this has been discussed prior, just tailing the end of this thread
