I have a GSX mini and X-16 too. I'm keeping the X-16 for now and have ordered Denafrips Pontus II.Since my actual "stack" is X16 --> Headamp GS-X Mini --> ZMZ Verite open, the X16 could be a "weak" point in my chain.
I'm still trying to figure out if a R2R DAC (like the Denafrips Ares II) could give me more instead of a 'simple' upgrade to X26 or another comparable delta sigma.
Yes, I really appreciate X16 and that's not helping this
Let's see how the Pontus does against the X16!
