I was replying to the other user about the verite, since he suggested it is much faster than the auteur and thus much better suited for metal genres
I listen to some pretty fast stuff, Ministry,Motorhead, Immortal,Parasite Inc. to name but a few,and I do not find the Auteur "too slow" in the least.
I used to own the Atticus which I adored,but that headphone I did find that the midbass got in the way for overly fast metal.
Is the Verite faster? Yes. But I enjoy the hell out of the Auteur,not only for metal,but pretty much every other genre as well.
Ive never heard the Ether Flow so i cant comment,but I have heard other Mr.Speakers headphones,and obviously by looking at my collection,I prefer the ZMF house sound over Mr.Speakers.
YMMV.
