Just wanted to pass along my recent experience of adding a Schiit Gungnir MB to the Node 2 that has been in my system for a few years now. I am using the coax out to the GungnirMB and balanced XLR into the Luxman 507uxii. The difference is so massive it's not even funny. I was hesitant thinking "how much better could it actually be?". It is better and by a wide margin. This has been a very good value upgrade for the result. I'm not going to get into making claims like it sound like vinyl or better that this or that because I don't have anything to compare it to other than the Node2 but it is so much clearer, plays to greater extension at both ends and has removed some digital harshness that existed when turned up louder. I still have the Node 2 hooked up through it's RCA - for MQA - and can a/b which makes it easy to tell the difference. I though that MQA from the Node would still best CD from the GMB but it doesn't. Not even close. I use this mostly for streaming but also have some music on a local NAS as well.
I would definitely give this a shot if you have the chance. Good luck!
