Which Pi Hat DACs measurements do you like to see

[Nango]

I think Aroio

Hmmm - I am not sure if you are mistaken: you linked the description of the Aroio OS which also supports IQ Audio cards alongside their Aroio DAC-Hat. As far as I can derive from their documentation the latter is an in-house design. It seems they used IQ cards till 2016 and switched to their own design late 2017 beginning with Aroio version 3.55.

They still sell an IQ Audio Hat on their website, but that's clearly a different design.

I'll write Abacus and ask.

I think Aroio is Abacus.

Your post is confusing me. What are you trying to say?

Abacus is the name of the company, Aroio is the name of their line of digital audio products, including Aroio OS and Aroio Pre-amps/DACs.

Yes, it seems to me, Aroio belongs to them.
