Bluesound Node 2021 vs Cambridge CXN v2 sonically worth the price difference ?

It's the wireless connection. 

@brianportugal

just in case you don't know

wireless can be wifi or bluetooth - they are not equal quality - bluetooth is vastly inferior to a (strong and well received) wifi signal into a streamer

Jj I agree Bluetooth is horrible for quality streaming. 
 

my sonica is working well except Tidal has made a change in software so I can no longer use tidal . I’m going to Axpona so hopefully I’ll find a streamer dac under 2k that bests my Sonica. 

I’d look out for the new Innuos Pulse Mini that incorporates Innuos’ latest thinking and gives you access to their Sense software that’s free and by all accounts gets high marks for both usability and sound quality and is constantly being upgraded and improved.  And Innuos also offers excellent customer support if you ever run into an issue.

Also, I believe you could add their upgraded linear power supply and get significant improvements and still be right near your price target or add it later when funds allow.

Hope this helps, and best of luck. 

Thankyou Soix. I have that and unit and the zen aurylic on the list . I heard the Altair is very good but out of my price range . I’m heading to expona so hopefully I can hear them in a system, but it won’t be mine. I can get opinions .
