Lumin T2 dac gone bad? distortion "spitting" "splatty" in mids/highs

I bought my Lumin T2 from Audiogon and noticed on many songs a mid/high distortion that sounds like a cable might be loose or a bad connection somewhere.  Finally after hours of switching out cables I decided to bypass the DAC and use my Anthem STR DAC (via usb) instead.  Spitting sound gone!  

Is this a common thing?  I found out that Lumin's customer service is in China and they don't have an 800 number so I had to email.  This ought to be very interesting.

Note: that most of the time the dac sounds fantastic!  It's only on those transients that I hear a "splatter" if you will at ALL volumes.

I assume you have tried just re-starting it. I have had this issue with my Lumin X1 a few times and that usually seems to fix it.
Also, check whether you are doing any digital processing either in your music software (Roon, JRMC etc ) or in the Lumin app, such as upsampling, EQ or conversion to DSD. I have found that this can cause digital clipping. If so, try turning all DSP off.

If that doesn't work, then wklie or your dealer are definitely your best bet.
