You can configure which source is selected via the Control app. I have to say that it was not obvious to me how to do this when I configured my first unit.

I think these 210’s are great, especially when synced with other rooms via Roon and RAAT which is not possible with the 218 as far as I know.

I currently have seven in my home audio setup and they work flawlessly.

Regarding the upsampling, I have one 210 connected to some old 16 bit 5000’s and it still sounds awesome. I just had to tell Roon to limit the audio to 16 bit for that particular endpoint.

I found that the best audio was achieved by completely bypassing my sound processor and so now when I select the 210 source I have a small relay board which activates and connects the 210 directly to the speakers.

The 210 connected to 8000’s is stunning.

Best Regards
