Hi Erik, Thanks. I'd tried that search on Amazon, Google, plus a number of well known audio dealers. I had emailed the area rep for AQ and was impressed to get a response incide an hour. He contacted their product dev who got back with the update:
“AQ was a bit late with the USB C cables that are available; we are only now finalizing C-to-C designs.
There definitely will be C-to-C cables, probably mid-summer 2019 — and they will be very good :-)
While it doesn’t directly address the question, an AudioQuest A-to-C cable used in combination with AQ’s ideal no-wire A-to-C hard adaptor is an excellent high-performance option”.
