Something to consider: As you wrote, it’s not Roon tested. So it’s very unlikely to get a resilient response from Official Roon support.
As Marantz claims that this device supports USB Audio Class 2, you should be able to hear sound – at least when you use PCM. I couldn’t see DSD over PCM (DoP) support mentioned for this device though. You should ask Marantz about this if you don’t want to take the risk and try it out for yourself. If it works you should be able to get DSD64 (DoP), limited by the 192kHz PCM support of that device. If you need more than that you may have to stick with an installation (endpoint) that supports the ASIO drivers for your device.
Update: I just found this older thread. Seems like you can get DSD128.
Thank you for your findings. Yes, I remmember that some time ago I found this thread about NA11 and Nucleus, but didn’t pay attention. Now I see that Nucleus is the same NUC with some kinds or 100% ROCK OS.
Your thoughts are the same which I came to as well. I may run W10 machine, however I wish to have a small server (like Nucleus, just cheaper a little bit) without any screen and without constant need to install updates etc.
For now I run Tidal on my Oppo 103 to feed NA11 via coaxial, however in this case Tidal is limited to 44.1 bandwich, no matter that Oppo succesfuly transfers up to PCM 192/24 from my local library.
As I tested on my main W10 machine Roon feeds NA11 with everything up to 192/24 PCM and 64 DSD (don’t remmember if I managed to get 128 DSD from Roon, which I did from JRiver).
It seems that I need to find some PC, load it with ROCK and then test with NA11. Thank you for your replies.
You know, I do research, I think about it, however in the end I still ask a question to get approvals for my findings and expect some official support. Thank you.
You can get support for Roon of course, but you can’t expect official statements about compatibility for devices that are neither Roon Ready nor Roon Tested. As Nucleus(+) and ROCK are both Linux based, you have to ask the device manufacturer, Marantz in your case, about Linux compatibility if you want/need some official statement.
