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.

What input on the STR do you connect the Lumin to? I imagine it’s what ddude003 mentioned, according to Lumin.

Some systems (perhaps with a high-gain pre-amplifier) may be better matched using the ’Low’ setting. It uses a combination of DAC settings to lower the output level by around -4db.
You’re just giving it some headroom it’s probably clipping on the transients.

If you bypass the DAC in the STR you bypass ARC room correction.
