I feel like the TH-X00 keeps a better pace with the music though. i.e. it sounds "faster". Maybe this could be because I lean towards the DT880-type presentation wtih the caveat that the HD600 has a better midrange and sounds more open than the semi-open DT880. I also think the HD600 has a more realistic tonal balance than the DT880 which seems like a headphone more suited to track or mixing since it has a more pronounced treble and drier less inviting neutrality. (lacking midrange bump that our human ears enjoy) The TH-X00 does suffer the treble "splash". Like you're getting a little bit too much at the end while the HD600 sort of rounds off the upper frequencies a little. I like the TH-X00 more from top to bottom but the HD600 does do extremely well with vocals and I think it was also at a disadvantage being paired with Asgard 2 versus the BH Crack. <-- could be why it sounded more "stuffy" or veiled. With HD600 connected to BH Crack it always sounnds airy and very ethereal like you are there. TH-X00 will spank the HD600 any day when it comes to electronic music and hip-hop. But I guess they both serve their purposes well and I can't say one is definitively better than the other since they are tuned more towards specific genres of music.
