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...

Wiim Pro. Amazon Music Unlimited . DONE.

My first foray into a separate streamer was the new Bluesound n130.  Definitely a step up from my Macbook air.  Super easy setup and works great with my iphone. Then, recently purchased a used Ares 2 dac.  I was surprised at the huge step up it was from the Bluesound dac.  I've been messing around with them both over the past few weeks and the Ares is just much better sounding to my ears.  

Anyways, now I'm thinking of buying one of these less expensive streamers like the Wiim just to see what the difference could be.  Maybe sell the node?  We'll see.  Long story short - if you already have a dac then try a stand alone streamer first.  It might be all you need.  Until you need something better of course!  ;-)
