most DIYer's have analysis paralysis, this list is going to be a problem for them !
It would make the list a lot more complex but it would be cool if there were indicators as to difficulty level, if pcbs are available and if they use any hard to find parts. A way for people to eliminate options quickly to narrow their version of the list.

When was AKSA 55 marked as DIY audio amplifier? I always thought there's a clone of AKSA based nd many other designs inspired from AKSA.. Or is there a diy version of AKSA 55? Am I missing anything?

You are forgetting one of the best DIY amps here, 200W CFA and 100W CFA versions
200W MOSFET CFA amp
200W MOSFET CFA amp
Where does the Self Blameless amplifier fit into this?
The Self Blameless Amplifier is not an amplifier design, it is a concept. Self implements the concept using a two stage amplifier (like the Honey Badger), but that does not mean every two stage amplifier is a blameless amp. Below is an excerpt from Self's book.
The Concept of the Blameless Amplifier
Here I introduce the concept of what I have chosen to call a Blameless audio power amplifier. This is an amplifier designed so that all the easily defeated distortion mechanisms have been rendered negligible. (Note that the word Blameless has been carefully chosen not to imply perfection, but
merely the avoidance of known errors.) Such an amplifier gives about 0.0005% THD at 1 kHz and approximately 0.003% at 10 kHz when driving 8 Ω . This is much less THD than a Class-B amplifier is normally expected to produce, but the performance is repeatable, predictable, and definitely does not require large global feedback factors.
Thank you for all your contributions.I think the list will expand further and very useful for diyers.

Performing simulations and all that nonsense with models of parts that you have no idea is even close to real world is absolutely useless if you want to know if the amp is any good.
A simulation gives you only some indication that in a perfect environment the circuit will work - how well is the question.
Sometimes you want blind people to listen and compare the performance - even more BS.
