I just purchased a Schiit Bifrost Multibit DAC. I have been using an HRT Music Streamer II. Wow! The Bifrost really opens up the music. Everything is sharper and clearer sounding. I am hearing bass I previously didn't hear before and the bass is more focused. It is like a veil has been lifted between me and the speakers. A while back I made a post in the Music section about the Bloomfield, Kooper, Stills Super Session album and how good it was sounding. Well it sounds even better today. Now I start saving for the Stereomour II or Kaiju.
