I am looking to upgrade my setup. At the moment I am using a 2006 Mac Mini lined out to a Denon AVR-1600 ->> 2 JVC tall standing speakers + Velodyne VRP 12 inch rear ported series subwoofer. That being said the sound is pretty good just with that, but I am looking to push it to the next level by buying a DAC. What should I go for? Currently I am looking at the Schiit BiFrost. Is that a good option?
