I own the Bifrost II from Schiit and the Denafrips Ares 2....The Denafrips in a fuller sound,,,,more meaty and well rounded. You can listen for hours and never get fatigued....The Bifrost is more detailed....deep soundstage....more exciting ...more crystal clear but not bright. They are different but both Awsome and highly rec'd. I've tried Topping and SMSL....not even close...They are both R2R Dacs...much better than chip dacs......good luck to you.
