Audphile1. That thing has been in both of my systems. Different cables, DACs. I brought my gear down and put it in his sysyem too to make sure it wasn't the MA8950.
I was doubly redundant. His A6 has been in my 2 systems 5 or 6 times. I troubleshoot daily in my line of work. I am extremely careful when trying to diagnose an issue.
Two different environments. Different ether and wifi. I tried to cover all bases before asking them for help. They just don't understand that poor support doesn't make for repeat customers. They'll learn this as they burn other customers .
