Cambridge Audio Azur 851N

I'm thinking of getting cambridge azur 851n vs oppo 105d for audio streaming and hooked it to my audio  research reference 5se and ARC ds450 amp. 

Do guys see or experience any issues with these set up? As far as i know the 851n has a built in DAC so no need to get a separate dac right?

any inputs/alternative please

This is an old question but I added an Cambridge Audio 851N to my system about a month ago and  what an improvement. I replaced my Jolida Glass Fx DAC with the 851n. I use it as a preamp with my Jolida vacuum tube amp in bypass mode. The results are astounding. I have a few terabytes of digital music including many hi-res files [DSD-DSF] that playback via 851n the 24-192 +playback is amazing. Note the blue tooth dongle is optional 100.00 I declined it sofar no problem I use WiFi. I thought for the 1799.00 cost it should be included.

While it should be included, Bluetooth audio is so compromised I'm fine without it. The BEST it can do is 16/44.1. It can play back hi-res straight off my computer without much fuss and DSF/DSD playback straight from USB flash drives, etc. Using the digital preamp mode is fantastic, finally brought my system up to date! 

Cambridge for the money is excellent! The British know their electronics! I have a 851N! Works Well!

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.
