I disagree, The D2000 I owned is even more U-shaped than the M50 and had harsher highs and more cavernous bass. The D2000 are an improvement over the M50 in some areas, but certainly not balanced tonality. I still prefer the M50 due to my preference for a less U-curved headphones.
Interesting that you think that. I was about to go compare the frequency response graphs of the headphones from Headroom, but for some reason the D2000 graph has disappeared! However, I remember that the M50s have a bigger bass boost on the graph than the D2000s do, which are extremely flat up until 1Khz or so. Either way, they both have a slight mid-range dip, and if my memory recollection is correct, the M50s have a bigger dip in the grand scheme of things. I know the graphs aren't everything, but it mimics what I've heard.
I wonder what might be contributing to the differences we've heard in these headphones. At times, the D2000s can be brighter than the M50s, but the M50s always had metallic sounding treble to me. The D2000s sound smooth, like what I hear from a silk vs aluminum tweeter. The M50s always had more bass for me, though. I was honestly expecting a bloated bass-monster when I got the D2000s, but I have yet to experience that. Maybe it's my source(s)? I've only listened to them out of my S:Flo 2 and X-Fi HD USB external sound card. I've heard the source and amping can really change the D2000s sound for the better, but it seems like the M50s don't benefit nearly as much as the D2000s with really nice sources and amps (FWIR and personal experience). They sounded more or less the same out of my iPod, S:Flo 2, Xonar DX, etc.
It could also be the version of the M50s I had. I've heard they went through a revision, and I don't know if I had the older or newer model. Either way, as a whole the D2000s sound more natural and balanced than my M50s ever did. They also have a nice soundstage and good imaging, where as the M50s sounded more claustrophobic/congested in comparison. The D2000s also just have more depth/texture/layering to the sound than the M50s as well. At least, this has been my experience, and that's all that really matters when it comes to personal audio equipment!
