Hello,
i have no doubt Roon Rock increases SQ using a direct connected Dac. But what about if using an NAA like the sotm sms? Is it worth the invesment in a i7 Nuc assuming a standard windows-pc running Roon already exists?
I can’t imagine, but there are a lot of issues in digital audio i never thougt they are real before experiencing 
Have a nice day
Carsten
