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.
