How to get DSD working in a networked (Roon) setup?

Dear all, just an update. I got it working but you'll never guess how.

I ran into the guide below, explaining how to install a music streamer on a Raspberry Pi4B. I had one laying around by accident. So I installed Volumio on it, bought a higher end 2m USB cable and it plays bit perfect DSD256 to my T+A MP 3100 HV. It's a bit weird to see a 150 USD solution dangling behind the T+A, but it works. 

To make it clear: with this Pi based solution, I can play (at least up to) DSD256 from a USB stick plugged in the Pi, over USB to the "USB DAC" port on my T+A MP 3100 HV. Config was too easy to be true, certainly compared to Foobar2000. 

Very odd it is Roon capable but can’t play directly.

I happen to use a Pi as a Roon endpoint, connected to my Mytek Brooklyn and never had a problem playing DSD at any resolution.

If you like Roon, may be worth getting a second micro SD card, installing Ubuntu on it and then Roon for Ubuntu/ARM.  Works peachy.

Thanks for your feedback @erik_squires . I've a NUC for Roon (the ROCK setup), doesn't it require more power than a Pi4B can deliver?

The challenge here is that my DSD collection is very limited and kept on a USB stick. Would Roon see the stick and be able to push DSD to the "USB DAC" gate?

I ordered a 4-pack of micro SD cards so could give it a go :)

Ah, I see the confusion.

I specifically mentioned it was an endpoint. My Roon server is another box with more cpu capabilities. The Pi is just for the Mytek. All my audio library is on a separate PC which runs the Roon core server.

You should just get a better roon endpoint, like a DAP that will play those DSD files without issue. Something like an Astell Kern Sr25 should do the trick and not expensive for what it offers sonically speaking.
