Devialet 120 Clipping...No Help from Devialet

[Confused]

I have a Devialet 120 hooked up to a pair of Focal Diablo Utopias I use Devialet Air on my computer through ethernet.  After my Devialet warms up I start getting clipping.  

I have this exact same set up (even the computer is the same) in another room and no clipping.  I have reached out to Devialet about 3 weeks okay and they asked me to remove the SD card and see if that fixed the problem.  That didn't...now three weeks later they are not updating my ticket or returning my phone calls.

Does anyone have some trouble shooting tips?  I have isolated the problem to the Devialet. 

Also if someone knows how to actually get ahold someone at Devialet I would really appreciate it.  I am really frustrated at the lack of customer service.  I don't think I will be buying another Devialet anytime soon.

I would go to the Devialet website home page during normal European working hours and try the on line 'chat with us' system.  I have used this once or twice to remind Devialet of an open query that is awaiting response from them.  It works quite well actually.
