Received a Schiit Gungnir and hooked it up through Toslink to a Cambridge CXC. First issue was a ton of hum. Schiit website told me to use a Humx. That was a new one on me so I researched the HUMX. A video told me to first test the DAC with a ground plug. Hum goes away get the HUMX. Still hummed so I told Schiit. Then I finished the setup and got continuous clicking while the DAC tried to communicate with the Cambridge transport. Back to the Schiit website. It tells me to get another transport. Really. I am supposed to keep buying transports until one works? Weird Schiit, right? After requesting a return authorization I was told it would cost 5% restock and shipping - damn near $100. So, in summary, the Schiit I got stinks and I get to spend $100 getting rid of the smell. WHAT DO FORUM WATCHERS THINK ABOUT THAT!! And by the way, I own two of their other products (Saga and Vidar) and used to have a third before selling it earlier this year.
