Bass quantity: D2000/D5000 > HE-400
Bass quality: HE-400 >>> D2000/D5000
The HE-400s sounded "bass light" to me when I first listened also.
With an amp, the response seemed to improve (though my ears had adjusted a good deal by then).
I went back to my old headphones seeking to find if the amp somehow helped them - nope. The old headphones, btw, despite a more aggressive bass curve, actually seemed "bass light" to me and, worse, lacking some extension which I had gotten used to hearing on some tracks.
Conclusion - the HE 400 are NOT a bass head's can. But for me to say that the bass isn't more than ample at times would be a lie. The response, volume, and texture are so good, you forget that good bass was, a year or two ago, just a prominent thump,thump, boom! The bass is a real part of the music with these cans, so other than feeling like I have a "perfect subwoofer" playing, the response is even and not really under or over-stated. It will depend mainly on the recording.
