Yes.

I'm an Audio Technica fan, not trying to knock the M50s
You can get a portable headphone amplifier for $25, Fiio or CMoy.
I've got to disagree - because the Denons' are simply not travel friendly phones.
The M50's aren't great in that respect either, but they're much better than the 2000's.
The 2000's are on the heavy side.
They're more delicate than the M50's.
The M50's fold; they're designed in part to be transported
The unusually shaped earcups on the Denons are very placement-specific.
And the Denons' fit is quite loose - very loose, actually.
The M50's don't clamp, but they do stay on.
The M50's will also sound fine without an amp (or
even better with a little Cmoy or Fiio),
Finally, this may all be moot anyway.
Because I've been looking and haven't seen the D2000's in stock anywhere.
Nor do dealers seem to have any idea when (or if) they'll ever be available again.
