I don't listen to any metal, sorry. On the good side, there's no problems here for me with regards to the D2k's speed. I mostly listen to instrumentals, EDM, vocal jazz, rock, classic pop and other random stuff like game and anime OSTs. I listen only out of the DX50 > 627 MICRO for everything which I think is a neutral to warm-ish combination though imo it sounds good with most any pair of headphones. I know the D2k is not the most ideal pair of cans for my intended purpose which is good all-rounded (to me, with my favourite sound signature being darker than most people's) comfy general-purpose pair of desktop headphones but so far it's working out pretty well. I'm now thinking of either selling my Q40s or swapping it with the HD25 ALU I loaned to my dad as its been overshadowed by the D2k, but I know he won't be too happy about that.
Here's another recommendation, and it's the kind of music that I most enjoy listening to nowadays (strange for a 16-year-old high-school student ):
Contains a few vocals but it's mostly instrumentals (piano, flute, violin, viola, double bass, etc). An absolutely beautiful set of songs imo. The D2k renders it amazingly and it's not too complicated either.
Sorry about that; simple case of good and bad luck respectively I guess
SUPRISE I enjoy the same kinda of music as well, classical is pretty swell!
Still for mids, the HE 4 is by far my favorite! It's got the sub bass extension of the D2k, the mids of the HE 500 and the highs of the DT 880!
