Advice on the best DAC to match with an Aurender N100


I've got an Aurender N100C with a Schiit Audio Gumby.  I just downloaded the latest Aurender software and the slight graininess I had has gotten more pronounced.  I'm thinking the Aurender and Gumby don't play well together. Any insights on good matches between the Aurender and another DAC?

I had an Aurender N100H and was using it with a Wyred4Sound DAC2 DSD SE dac.  It was a $2700 dac and the main reason I sold both pieces was because of the graininess.  My Sony HAPZ1ES at 2K totally out performed the above combination with no grit or grain.
Hi pg62,

I have a N100H and have been happy with the sound when paired with an Exogal Comet Plus and a Denafrips Terminator, both via USB. 

I also have found it sensitive to power cords.
