@zlone have you had any reliability issues with the components that you own? My biggest concern is the Loki Max sending any spurious damaging signal downstream into any of the components..
I have an original Gungnir that I also shipped back to upgrade to a Gumby. That has worked flawlessly. My first Freya + had problems in one channel when I received it and it had to be returned. But first they walked me through some tests to ensure it was not just a tube problem. My second Freya + arrived and it had a loose part inside and they agreed to let me open it up and resolve the problem. It was a simple fix to restore a clip on heat sink. You could call these quality concerns, I say Schiit happens. All correspondence was timely, and in the latter case occurred as they were evacuating their buildings during the fires a few years back. I see a company that works hard to deliver a high value U.S. made product, and backs it up. My only advice if you ever need service, have some patience, and never be a jerk, you might find yourself at the end of the line.
As for your specific concerns regarding spurious signals, unless there is a basis for this concern I would not worry too much. Reviews I have read on the Loki Max have been pretty favorable. That said, everything affects the sound, and looking at your system online, it does not seem inline with the level of gear you are running.
