@dhite71 It is not a new unit. It is a demo unit which is more than a year old. I would not ask a dealer to open a new unit for audition purpose.
Anyway I have moved on and just received my Grimm MU1. I just connected everything. Unit is getting warmed up. Very simple to set up and so far no issues. I selected 1.6 TB of music to be transferred to internal drive. I will do the transfer overnight. Once again appreciate all of the responses in this thread.
