Well, I haven't seen any spec on this cables, but have provided link to Canare specs. I'm not a cable tester.
As far as the shield, it looked like cloth. It would be good if your mil spec cables had cloth covering as well as the wire, as this would reduce handling noise..... oh, ya, those mil spec cables are not meant for handling...... they are for permanent installation. I'm a fan of using the right gear for the right job, and these mil spec silvers are not for mic or line signals recording location sound!
