My first run with them was this morning. I cannot say enough good about what I've briefly heard of them. I let Sarge clamp the cans on, and she commented on how clear it sounded.
I record quite frequently in this room; noisy HVAC is my worst comment about it. Its a nice sounding room, just noisy.
I ran Gude Head as both Senn. protocol binaural, and, with the new MKE2 pair on Gudes head, as HRTF stereo. I also ran the cm3 pair as XY_90º as a "control copy", in case the building got nuked, and Gude exploded, the old folks started into slam dancing, or whatever.
All acoustic, except the vocalist.
