I agree with @audphile1 Keep the node until you can save up for something better.
I owned a Cambridge CXNV2 before my Arender N200. The Aurender is far better. The CXN was good and had a good sound as a stand alone unit, I didn’t like that it didn’t cache the playlist and would sometime pause or delay the music. It would mostly be a lateral move from the Node for you. UPscale Audio has an Aurender N150 open box on sale right now. Good luck!
