new small adc ...

I didn't find any mention of what ADC is used inside the Mini, but it's probably worse than that used in the Pro.

It is not a DA converter but an AD converter. Based on specs and measurements it is better than she AD converters onboard the various WiiMs.

Better in what way? Better noise level maybe but does it matter?

The ears would have to decide that.
Technically (according to specs) this little ADC is about as good as such things get and transparent for all practical purposes, and on par with the best WiiM DACs. With this device the one could achieve transparency from analog sources on the Ultra and Pro Plus.
