Has anyone used an Asustor NAS with Roon ?
Yes. I use an Asustor 604T NAS connected via ethernet from modem. Then modem ethernet connected to my Windows PC. Works fine. I do have a rare occasion where Roon will throw an error and suddenly stop working. Since this could be a number of reasons - possible network dropout or NAS hiccup? I usually reboot the NAS and router and the error doesn’t come back for a while.
Related to Roon I just use the Asustor as the source for network audiofile sharing, works flawless. In my case Roon core is installed on a computer (which is connected with a DAC).
