Can anyone recommend a good streamer/DAC?


I have tried streaming on an Astell& Kern Kann Cube and love it. Now looking for a streamer DAC combo (or  both integrated in one box) to put on the rack with my living room system. I have read good things about the Cambridge Audio 851n and their CXN v2; $1,500 and $1,100, respectively. Also about the Bryston BDA-3.14, at $4,200. I am willing to pay for good quality sound and at the same time I worry that the technology may be moving fast enough that as with computers and HDTVs there will be a much better version available soon for a lot less money. Anybody know if Cambridge Audio or Bryston has anything new in the works for streamer/DACs? All recommendations will be much appreciated.

The Naim series like the nd5xs2 is great at about 3500 ( I own one of these), and the Araulic Vega series, g1 is about 3500 I believe and I Just purchased their g2.1 which runs 6900.00. Both those are very easy to use also, which is important to me. 
Many thanks for the insights and helpful suggestions! What a pleasure to get your  thoughtful replies.
I’ve already got the BlueSound Node 2. The 2i fidelity-wise is the same. I’m happy with it, but I’m looking at offloading to a DAC to improve the sound even further. Two that have caught my eye in particular are via the links below. The MyTek fully supports MQA, which is nice since I primarily use Tidal HI-FI. The second, the MHDT Labs Orchid especially caught my eye because it has top notch processing and its tube based for a very affordable price.

I had the CXN and while the SQ was very good the controlling software via the app was useless, particularly if you listen to classical music.
