Difference between Cambridge Audio CXN and CXN V2 and other Network Streamers


So I am looking for a Network Streamer and the Cambridge CXN and CXN V2 come up.  From what I read the V2 had updated processing power but when I compare the two the DAC and Analogue filters are the same.  Is it worth the extra $300 clams to go with the V2 or get the CXN and look for a separate DAC (a Schiit or something).  I do see the Azure 851N is a significant jump with two DACs and is CA's premium streamer.  Also throw in the Oppo Sonica, is it a fair comparison to the CXN variants?  Anyone have any experience or insight with these network streamers.

I own both 851N and CXN V1 both.
the 851N is a premium feeling and the DAC is almost as good as Chord Dave!!!
the Dac on 851N has overtake the Hugo TT2
which we try on the same wiring.
The analog part we use is Nakamichi amplifier 1 and PMC 25.26
the sound is marvelous!!! Everyone in the room was stunning!
We use SACD and Streeming with same alabum.
The Tidal over take the SACD but spotify was poorer.
Next time We will try it with CXN V1

I have a change to buy the old version CXN V1
on a discount price my question is if the old version can support the main striming services like Tidal,Deezer and Quboz ?
If I update the V1 is it basically the same as the new version V2 ?
