I have been using the BlueSound Node since July... I really like it...

Sound Quality with the new DAC chip is very good

The Streamer is BULLETPROOF, I am using WiFi and have not dropped a song once...QoBuz exclusively 

The App/OS is outstanding...The interface is the best in the market, easy to use, easy to set up...

Gapless is a must and the BlueSound supports this...

There is a MASSIVE amount of choices /pricing (and opinions) on this component segment...and a ton of excellent data on this site...enjoy the journey!

I went with the "ZS is better in SQ than Node" flow and was very happy with it. 

Can you mention that reason, and why it’s “complete shite” for streaming non Hi-Res files?

@surfmuz Because the OP mentioned the Node 3 and Zen Stream, and next to them the Chromecast Audio is at best a toy. And as Spotify now offers higher-quality streaming options a better streamer would provide meaningful sonic benefits over a toy. That’s why the CC Audio is shite on a relative basis. Also, you can read Darko’s review of streamers where I think he may have compared the CC Audio to the Node and some others and it was complete shite. So yeah, in the context of the question asked by the OP the CC Audio is just not on the same level.

The Chromecast Audio 30-40$

Bluesound Node  500$

Zen Stream 400$

These are just basic streamers, some are better than the other. Buy used.

Which one to choose depends on what demands you have from the system and what upgrade plans you have for the future. 

Try the Grace Digital Link, on sale at Amazon for $159....I love mine...
