I got mine about a week ago on the same day that my Tin Hi-Fi P1 planar IEMs arrived. I just spent a couple of hours listening to Tidal MQA files and other things on my phone using the supplied USB-C (dragon tail - great name) cable. This is a fantastic combo! It is amazing how good portable sound has become.
I will probably bring the Cobalt to the next meeting on August 10th at Russ's place.
