@khiak First, congratulations on your T+A SDV 3100 HV.
Since you are "new [to] streaming" ... as a starting point I recommend going with Tidal first. That is Tidal direct, versus going through Roon.
The SDV can accept Tidal Direct wireless or via your CAT7 cable from your router. You can control Tidal via your iPadPro (using Tidal's App) OR directly via the T+A Control App which offers Tidal, qobuz, Deezer, control.
