I have a Media Server with ROON installed on it. How do I setup a Roon Ready access point in another room that I can use for late night Head phone listening?
That’s a very open question with many variables.
You will need a network connect Roon Audio Endpoint, a DAC and an AMP.
Lot’s and lots of options, from DIY like a Pi + Hat, to Roon Ready devices like a sonicObiter or a MicroRendu, tt could even be an Android tablet.
Have a look at the Roon Partners Page, anything of interest there?
Do you have a budge in mind and what type of hardware are you most comfortable with?
