Any recommendations for aftermarket C-7 power cord for Bluesound Node 2i

@vinylshadow Lumin and others make streamers only. I was seriously considering the UI Mini before I bought the TEAC. The biggest downside to the TEAC is that there is no digital out, so you are committed to its DAC. It has a great DAC though. 

Save your money for something better than the Node 2i.  The Node 2i is a great entry into streaming, but if you get to the point where you want to improve sound quality, don't throw a bunch of money into cables, external DACs, etc, just get something better.  

I don't disbelieve people when they say a power cord or internet cable or whatever made it sound better.  Maybe their hearing is better than mine and they can detect more subtle changes than I can. 

However, I did many of those things, "better" power cord, better cables, external DAC, etc.  The only thing that made a difference was the external DAC.  What took streaming to another level was replacing the Node with a better streamer.  Everything else is a band-aid for a mass market device that is nice for its price, but not really an "audiophile" component.

@vinylshadow I replaced my Nodes with the TEAC NT-505.  Bluesound has a better interface, but the TEAC is more detailed, warmer, more "analog" sounding, and has a noticeably larger soundstage.  I would also look at Lumin as an upgrade path.  

@rareace I tried a lot of things to make the Node sound better and some helped (an external DAC made a noticeable difference).

I'll have to take your word that a PSU somehow magically transforms a mediocre streamer and DAC into something magnificent. I'm not an electrical engineer and never heard it, so I could be way off base, but that doesn't pass the smell test for me.
