Hello and happy new year to all!
Being sort of a multilateral character, my dreams always are several steps ahead of my mind.
Just like my DCG3-build: Not quite finished (almost done, but still not even heard how good it is!)
It is my second build with an opamp in the circuitry (bugle2 being the first), and opamps are like capacitors—there's rumors they can be rolled 🙄
There aren't many mentions in the build-thread, and I am basically clueless, so I looked up the datasheet for the AD823ANZ in use (here), which left me quite as clueless as before.
Then there's the store's Burson Audio V6 offer, where AD823 is mentioned as "AD823, AD823AN", but no "AD823ANZ".
How to discern the variants, and what are the differences anyway? (between the AD823 to start with)?

You would need to look at individual data sheets but typically the differences will be packaging, lead (Pb) free and things like extended temperature range in use.
From your link. So the ANZ is the 'big' 8 pin DIP package we all like 😉

If you want to play with opamps then be aware... mostly its fine and its fun but sometimes...

Ignore rumours propagated by audiophiles on the internet.
Ask yourself what function in the circuit does the op-amp perform and what characteristics does the op-amp require to carry out this function. If you don't know or are unsure just ask.
Learn to understand op-amp datasheets and what parameters are relevant to any particular circuit.
Once you have this answer, did the person engineering or designing the circuit undertake the same methodologies ?
Without this information it is just a process of randomly changing components without any understanding of what the outcome will be.
