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.
I own a T2....very satisfied and absolutely no issues as the OP described. Some good suggestions provided. I have interacted with Peter Lie, who is the "head" software designer for Lumin....if you post on the Roon Community forum under Lumin hardware you will get his response plus others I'm sure. Please let us know how this turns out.
