In direct comparison between CRBN 2 and MK1 007, CRBN has more midrange clarity and the vocals are warmer and fuller. The vocals are probably my favourite aspect of the CRBN 2. The tonality is good but becomes an issue when listening to classical or orchestral as it's too dark and the 007 has more sparkle.I would say though that it's not just about being warmer or with just better bass. I *do* think both CRBNs do an amazing job with tonality overall, similar to the HE90 and I'm sure the HE-1 from what I read and have talked to people about. The 007, although bass sufficient and warmer, does have it's own quirks that the masses don't necessarily agree with. Same with the 009, Shang Sr. and others. What complicates things extremely here is that there a few variations of the 007 that have less quirks. But majority of 007s that are in people's hands is what matters most imo, not rarer versions with slight variations (although those that have them are lucky!). I mention this because I suspect your 007 is possibly a bit less dark than average and possibly has more clarity than the CRBN. In general, I've found both versions of the CRBN to be very close to the average 007 but not ass dark specifically.
So in general I will give the CRBN the credit it deserves in having transformative tonality overall that very few stats can match.
The HE1 is a headphone with zero weak points. We have always chased a headphone that can do it all with zero compromises and you will get that for a very hefty price! I guess you can just live a care free audiophile life with one instead of always chasing something lol.
