I just received my new Zbit today. I have a DAC with balanced outputs, but have been using the coax outs since I got the DAC about 6 months ago. I absolutely cannot believe the difference that the Zbit makes using the balanced outs on the DAC!  Better bass and much more depth and detail. It’s shocking how much better it is!  I got a used Zstage a month or so ago that made a big difference in my phono setup, but nothing compared to this. Highly recommended!!!
