I owned D2K and those had quite harsh treble.
Anyhow, I've been really enjoying modded D5000 with Lawton Angle pads for the last two days. I think i like them quite better than Alpha Padded Mad Dogs, they might be more colored but sounds like a lot more fun.
This is quite funny as they were on a chopping block for a while as I just couldn't stand that pumping into ears bloated bass, was just getting headache after a short while.
Modding with dynamat helped with that, bass got much more controlled and quite listenable, the only things that still sounded off to me were relative to bass recession in the mids, "busy" sound i.e. when music gets complex things start to mesh together, and treble that was missing extension at the top, hi hats and brass instruments sounded muffled. I wasn't expecting much from Angle Pads but to my surprise they evened out mids, added more air between notes and that missing zing to the treble. The bass is still hitting hard but does not bounce around and very controlled although perhaps some amount got lost, could be just reverb and bloom that are gone.
