Here is a guy who is struggling with he's X9K review
i think this is the third try from him to understand how the X9K sounds
he mentions in he's latest video that X9K has midbass hump, i have to correct him, it has not, maybe we see he's fourth video where he finds this out.
I have compared lately 007 to X9K and X9K is significantly better. I also have the feeling that X9K suits well with tube amps or at least you then have to have a tube front end
Tube dac or tube preamp. I heard X9K with a tube amp and it was perfect.
If he really knows what his audio perferences he wont shift his opinion back and forward like that, the 007Mk1 is a very nice headphone for sure but it didnt have the high resolution and modern touch of the X9000, and I am sure the X9000 is better than the original Omega which in many ways is better than the 007MK1.
