Why would I need Roon?

You can get a 30 day free trial. Try it and see. Great way to find new music you like as well as providing useful information about bands, performers and their influences

I don't know that you need roon but the reason I got roon was the user interface and sound quality. In my subjective opinion as I never tested blind is roon has better sound quality over my Node2i, both with my ripped CDs and Quboz. I like the user interface a lot better and the fact with roon I don't really need a dedicated streamer. I let the core handle the streaming and use a roon bridge with RAAT to connect to my DAC. The DAC controls the clock of the stream and IMO gives me a nice simple solution with excellent SQ. 

Ok...finding new music...I hadn’t thought I needed that, but an interesting angle. Information on tracks is a an important plus.

@djones. Good to know. I only recently bought the Node so I’m feeling squeamish about ditching it yet.
