Sword of Damocles
100+ Head-Fier
Thanks for your review and measurements! It was a good read.The Caldera Closed is up for sale now and so is my review, all 6 pages of it: https://www.techpowerup.com/review/zmf-caldera-closed-planar-magnetic-headphones/
Edit: It's published now
Caldera Closed just might have made Hifiman Sundara Closed more interesting.
