I was in the same boat and decided to go with the CXN at the new reduced price and I have 30 days to return it. Been to listening tidal with the CXN the last couple days and it sounds very good. If I had to make decision right now, I'd keep the CXN and pocket the difference between it and the 851n.
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.
