Cambridge Audio Azur 851N

I have an 851N. And am completely happy with it.  I also use it as a preamp-- I had a Nuforce mcp 18a  but could not tell the difference. I have Bel Canto 500m mono blocks with Dali Mentor 6 speakers.  Also use a Marantz SA 8004 as cd transport.  Couldn't be happier with the 851N as streamer (FAT 32 USB). Sound is excellent, whether as steamer, DAC, or Spotify. 320 bit internet radio also very good sounding. I had a Marantz streamer but returned it because of a buggy user interface. The Cambridge interface has been flawless. 

@tomaswv, Can you stream Tidal Hi-Fi on 851N? I know the streamer has a built-in support for Spotify.  

I have not tried. To my knowledge there has not been a firmware upgrade for Tidal, but of course there may be other ways to get it. I keep thinking Spotify will add a high Rez service, and haven't really explored Tidal or other services. Been buying high Rez downloads now and then, but quite happy with red book and streaming off of my hard drive.  I use Spotify mostly to check out new things or carch up on bands I missed along the way. 

You can get Tidal through Apple  air play. The  dual Analog devises 1955 dacs 
are very music ,with the Swiss Anagram Technologies receiver  top shelf 
and everything upsampled 24-368 truly puts noise way out of the audio band.
100s of digital audio radio stations  wifi  which sounds better then blue tooth.
your hard drive plugged in sounds great very good detail and natural warmth 
not bright  sounding others like benchmark 3 a bit better leading edge but does not have the musicality in depth of image .the supplies to the Mytech Brooklyn dac .theysound good  but if you want a bit morgrip and body without being syrupy warm Analog devises has been a class leading designer in the U.S
for years. One more thing almost 18 lbs, big internal Torroid transformer ,and power supply for digital. the Sony was good but older technology 
it does have a built in hard drive . He external drive is easy to remove ,and replace with solid state drive or any  Nas drives.

Only via AirPlay or with any computer attached.

For those who enjoy the convenience of Bluetooth, you can play media straight from a WiFi connected smart phone or tablet, which @audioman58 pointed out above.

It may be off-topic, but I enjoy my 851N so much so that I recommended the CXR-120 receiver to a colleague. The setup was difficult and the user interface is nothing like the 851N’s. I had recommended it to another friend but revoked my recommendation based on this experience. This happened before he got around to purchasing it (phew!).
