Personally, I think you are better off with the NODE. It is half the price of the Cambridge and has a much better user interface with BluOS. The NODE has native integration with just about every streaming service with the exception of Apple Music (and it does have access to Amazon, despite a previous post). I can't comment on the internal DAC on the new NODE, but I have the Node 2i and I think its internal DAC is very good. I do use an external Meridian DAC (which I had already owned) and the difference between the two DACs is very subtle.
Both units support Roon, Apple Airplay 2 and Google Assistant. The NODE also supports Amazon Alexa. The NODE has BT built in, but it appears you need to purchase a separate BT adapter for the Cambridge? But you seem to be focused on hi-res, so BT may not matter that much to you.
