Roon ready endpoint with physical volume control on optical out

Hi,

Do you guys know if there are cheap roon endpoint streamers / dac / amp / all in one etc etc with:

  • physical volume control (knob / buttons / slider / etc) that affects digital out (and not just analog out, like CA cxn2) like cocktail audio N15D or bluesound node 2 perhaps?

OR

  • same feat but not roon ready but with USB input (and possibly roon tested)

So far, I found only cocktail audio N15D and bluesound node 2 (but i’m not sure of this one).

Do you know other streamers?

thanks
