I have it also, the Yggy DAC with the N100H. Excellent sound; you'd be hard pressed to get better at any price.
However, when I first got the units about seven years ago, I had problems with uncompressed .wav and .aiff files larger than 400MB not playing. Aurender had to reprogram the unit to disable the 32-bit output because it was hanging up the DAC. Don't know if that is still an issue today.
