Very interesting. So, you don’t use HQP + Roon? Just Roon? Have you compared the sound of HQP + Roon to Roon only?
Even if you run Roon exclusively, you would still need a VNC client to update the operating system, format an sssd drive or check how much space you still have.
I use Roon exclusively at the moment. I have all Windows automatic updates turned off and Roon updates can be executed from an iPad.
I keep all my music on a NAS - I upload new music all the time and it just shows up in Roon instantly by itself. I don't have to touch my server in any way - via Remote Desktop or otherwise. Roon iPad app is the only thing I use.
It doesn't get easier than this.
