Everyone has confirmed the importance of the DAC as well as the vast range of quality across all the options available. I tried the Vault 2 a couple years ago when I had ARC separates. I could only go analog out of the BS into my preamp and was quite disappointed in the SQ compared to vinyl. I resold it and forgot about streaming. A few months ago I took a leap of faith and got the ARC GSi75. I sold all my separates and am loving the new system. Streaming was not my goal of the purchase but as I read review after review it seemed there was a special DAC on board. I picked up the Node 2i and connected via the coax out and I was blown away. I also compared with the analog out into one of my SE inputs so could easily A-B these two options. The analog out is pretty much that same SQ I had before in comparison to vinyl. The GSi75's phono preamp is also of surprising high quality. When I am using the ARC DAC the SQ is incredible. I mostly prefer the sound of vinyl but there are occasional albums that sound almost the same or slightly better. My streaming service is Amazon HD. I did a trial with Qobuz and Tidal. I found their sound the same and Amazon offers a better value for me with other devices in the home. There is MUCH better sound to be had from your Node2i...you just have to find the right component for your budget and system....don't settle on the analog out.
