I own the ARIES G2.1 and absolutely love it. The app is superb and the connection to wifi has never failed me, which was a big part of my streaming needs. It’s built like a tank, and does everything I need from it with no fuss, which again is a major part of what you want from a streamer. Very much a fit and forget product, other than how nice it is to look at.
I too was looking at the Vega G2.1 because of its superior connection to the ARIES, however the Chord TT2 is much better value and provides all the sound quality through USB, despite some peoples assertion it’s a terrible connection. Speak to any dealer, I speak to plenty, none of them state USB isn’t a good connection.
If you have a link to the power supply upgrade I’m interested in that, I haven’t seen anything on it before.
