I used the internal DAC of my Wiim pro plus for about a year, but after a while came to the conclusion, that the Sound lacks a lot of the attributes I love about my Vinyl Setup. And as i digged into the rabbit hole of DAC Systems, I soon found out about Denafrips.
To put it short, this comes very clone to the vinyl sound, and absolutely makes a huge difference to the Wiim dac. So open, airy, wide soundstage. Listening fatigue is gone and it just makes me want to Listen to my digital chain more often.
Definetly recommended!
