Hi everyone! Brand new here. I'm a music teacher and finally upgraded my personal listening setup. I recently bought a Shanling M3s and an RHA Dacamp L1. Both are nice devices! I'd like to use them together via a USB cable rather than 1/8" audio cable. I connected them but the connection only worked once. Ever since then the Shanling won't connect to the RHA via USB. I tried different cables and using different firmware on the Shanling but no success. Any ideas? Thank you!
