AFUL SnowyNight Dual CS43198 USB Lossless Stable Transmission Portable DAC & AMP 

I have just picked up the Aful Snowy Night.. love it.. clean and clinical.. yet warm... its not a huge upgrade from the Simgot Dew4X but it is a sufficient upgrade and glad I got it.

Thank you for your review.

What is meant by grainy? Is that an artifact in the treble or overall sound? I’ve never heard a grainy sound before.

Ian Freaking Fann!!! How you been man?

What IEM did you use to test it? And which dac is your favorite?
