I agree with the comment above. That upgrade is really easy and will breathe some new life into your G1. Keep in mind that (in my opinion) you'll have to spend a bit to beat what you already have. I compared the rose 150 to my modded G1 and I ended up sending the 150 back.
Is My 7 Year Old Aires G1 Still Relevant?
My Streamer/Server is an Auralic Aires G1 that I got when it came out in 2017. It still does everything I want, but has the sound quality improved over the years by very much. Currently my DAC is a Laiv Harmony through USB connection. I was considering one of the new Auralic Altair G2.2 as an all in one box, but if my G1 is just as good as today's stuff, at comparable pricing, that will open my choices to a whole lot of DAC' with a remote volume, but no streaming capabilities like the Altair.
