@sandyboy101 I have experience with the Bluesound Node 2, Cambridge CXN V2 & the ELAC Discovery.
Last week I auditioned both the Node 2 & the new Node 2i with the NAD Masters amplifier and PSB floor standers, I was not that impressed with either of them. I was left with a feeling that there was more to the music that the Node 2s were not showing.
The new Node 2i had a lot more details than the older Node 2 but I didn't feel it was presenting it in a pleasant way.
As for the Cambridge CXN V2 & the ELAC Discovery, some time ago I auditioned both of them at a dealer, who happened to stock them both, the rest of the chain was the Musical Fidelity Nu Visa amp & Elac Line 407 floor standers.
I had a strong preference for the ELAC Discovery, it was richer, smoother and more laid back and had all the details I needed. The CNX was a bit harsher on the highs and had a more forward & thinner sound.
Sound wise, between these 2, I'd say it really depends on the rest of your gear and your preference.
I personally prefer the ELAC Discovery, I used to own one & regret selling it to a friend, im now plotting how to buy it back from him
Another thing to note with streamers is their control App, I found the Cambridge App garbage for playing Tidal. The BluSound & Roon (essentials) are by far the best out there along with the Naim app.
