Mola Mola Tambaqui is great sounding for the money. I am using Zenith SE with mine.
A few recommendations:
1. The Innuos greatly benefits from isolation: Nordost SortKones (BC or better yet TC) and even better Stillpoints.
2. Synergistic Research fuses on both.
3. Get a really great USB cable.
4. And… most importantly: The Innuos Sense app sounds significantly better than the Roon (I use both as I prefer the Roon experience but Sense SQ is superior). If you are going to use the Roon: try converting the output from flac to DSD64 or DSD128 inside of the Roon system. I have found this results in the most natural sound and best overall SQ for Roon… The Tambaqui loves DSD signal! But even this doesn’t quite get to Sense level.
Good luck!
