With the type of resolving gear that your have, Wison speakers powered by D’Agostino amplification, feeding HolosSound Dac, it is my opinion that you will hear the difference as you step up the ability of your network player.
I agree that the Bluesound kit is great value for the money. I too am running Roon via a Roon Nucleus, and own various pieces of Bluesound kit including a Node 2i. I had been using my Node 2i in my main rig feeding a Chord Qutest. After acquiring the Roon Nucleus in 2019, it replaced my Node 2i as my principal streaming source, feeding the Qutest directly via USB (Curious USB Cable) with the Nucleus being powered by an Sbooster 19v Linear Power Supply. I felt this was a step up from the Node 2i (not a giant step up, but a step up nonetheless). A few weeks ago I acquired a Bricasti M5, and this is a giant step up (lower noise floor, more air, improved soundstage, etc...) feeding the Qutest via digital coax.
