Just finished a 5am remote session with Innuos tech.
2 hours and viola!
I’m back up and running.
In end, they said it was the HID method that Marantz/Technics use. They had to turn off settings that conflicted with the DAC (internal DAC of my SA-KI Ruby).
They mentioned that it should be OK restarting from now on, unless there is a specific sequence needed, but best procedure/practice is to power on the Zen Mini MKIII before the SA-KI Ruby.
Shout out to Nuno Vitarino, R&D Director and Laurent Gansen, Customer Support Engineer at Innuos for stepping in to help a customer in need.
Exceptional customer service and support.
