I just added the same Cambridge streamer that the OP uses. I bought it because of its claims to use mpegDASH to improve Internet Radio, and because I wanted to add an AirPlay device to my two channel system. Unfortunately the RCA interconnects from Audioquest didn’t arrive so I had to use some cheap RCAs that I had laying around to connect to my pre amp.
On the + side, it had no IT issues integrating into my system via Ethernet, and the Cambridge Connect App seems well thought out. The AirPlay works fine On the minus, I was disappointed that BBC Radio3 and my other favorite Internet stations are still showing a bit rate of 128kbps or below. The Cambridge recognizes the files on my Melco N100 NAS but sounds pretty thin compared to both the Melco and my Oppo 105 playing the same files into my Bryston DAC.
I haven’t tried playing the Cambridge into the Bryston DAC —I’m out of cables for that as well. Also, the Cambridge appears not to work with Qobuz. Is the OP. using his to play Qobuz? I can still play my Qobuz files with the Melco, so not a deal breaker, but I’d like to know I had a Bluesound Node2 last week and to my surprise the DAC on the Node2 sounded much better, although the cabling was different.
What to conclude? Nothing at this point. However it does reinforce my belief that when deciding what works best, streaming or CDs, it depends on the individual players
