I recently received an SMSL SU-9 and SMSL DA-9 from Apos Audio. Most of the time when powering on the DA-9 (by pressing the front knob), the device will hang on the "S.M.S.L." screen without fully booting up. If I unplug first from the power outlet, then power on, the DA-9 boots up. Is this a common problem that is hopefully fixed with a firmware update, or do I have a dud?
Thank you
