Is it worth it? DAC question

The iFi Zen appears to have only a USB input. You can only use it if you have a Node N130 or Node X.

Thanks again for the good advice---I've got the cables to connect just need the 5v adapter then I'll try it. @parker65310 Good to know about Silnote Audio--I'm in VA, will def check them out.

I have a Bluesound Node 2i that I use as a streamer only. I  have it connected to a PS Audio Directstream DAC, and the SQ is magnitudes better than the internal DAC.  I  would have purchased a more expensive streamer,  but I can't find one that supports both Amazon music and Idagio.  So I upgraded with a TeddyPardo LPS; I was very surprised by how much the lps improved the sq. Better bass, wider and deeper soundstage, and improved imaging. And a quality digital cable does make a difference,  despite the " it's just 0's and 1's, so it gets it or it doesn't " argument. 

Hook up a USB cable from Node to DAC. You don’t even have to go into Node settings to enable USB output. Listen and you decide. 

OP,

It really depends on which Node you have. The Node 2 and Node 2i DACs aren't very good as previously mentioned, the DAC in the Node 130 is better. Some have recommended the Teddy Pardo LPS, but at $425 is rather expensive. I use an LHY LPS which at $279 is more cost effective, and for me yielded surprisingly good results.....however I have a Node 130. Only you can tell which DAC is better on SQ
