Schiit Gungnir

@infection - I have not owned the Gungnir, but I did own the Bifrost

My issue with both of these DAC's is - they share the same USB port circuitry - which is powered from the USB power from the computer and as such - both will suffer from the problems associated with computer USB power - instability and noise!

To combat this issue I purchased a V-link192 USB to SPDIF converter, which improved things greatly. 

In addition to that I also purchased a dual lead USB cable from Doukmall and a separate power supply

I have since changed to the Bluesound Node 2 - which completely outperformed the Bifrost/Vlink combo and is easier to maintain.

If I'm not mistaken, I think Schiit is *currently* (as of a month or so ago) including their USB Gen 5 boards in any of their products where applicable. If so, that is supposed to solve any and all "issues".

Glad to hear it - it was a big disappointment for me that's for sure.

Cheers
