The Bluesound Node 2i is a cost effective high quality source. Since you don’t own CDs, why buy an all-in-one budget source like the Marantz? All electronic devices are in one box most likely using a shared power supply.
The Vault would not make sense in your situation since it has a hard drive to burn CDs. I think the Node would suit your system....there is a trial period with the purchase and each streaming service offers a 30 day free trial.
If you were to go for the Node 2i, adding an aftermarket power cable and a high quality digital cable will vastly improve the SQ. Music becomes more transparent and realistic.
