I'm not sure what the question is...
I'm also not sure what could possibly be a problem with CCA cable, other than reduced malleablility, as the difference in resistance is small.
Aluminium cabling has been used rather successfully for electrical generation, transmission and distribution, so I'd love to the see the arguments against its use in somewhat less critical applications (hifi)- it should make for chuckles if nothing else.

Aluminum in voice coils is used only to reduce the weight of the mobile system. There is nothing better for this. The best voice coil was invented in the USA in the 30s by Bell laboratory. He wound a flat aluminum wire ribbon around the edge. Karunda ceramics used as interturn isolation. Even now, in the 21st century, not all firms can afford this technology.
Some speakers from the French company Audax also use voice coils wound with flat tape around the edge. But they used copper as a flat wire material. To save the mass of the mobile system, they were able to significantly lighten the mass of the diffuser using the latest at that time airgel HDA.
The use of aluminum conductors in electrical engineering was associated only once with cost savings. Now they are moving away from this, since it is much more important to get an economic effect with long-term operation of equipment, which more than covers all initial savings.

I got some 12awg cca by mistake from the hardware store (thought it was a little light, but was in a hurry!) got home figured it out but tried it anyway.
In a straight up comparison against regular copper 12awg zip cord the difference is beyond noticeable......the cca sounds dull and lifeless.

You are free to think any way you want. Key point is, which evidence is your thinking based on?
Electronics engineers are not immune to placebo effect, expectation bias, sound difference caused by listening position change,... etc., the usual culprits of subjective listening results. Why? Because they are people just like you and the rest of forum members.
The proof is very simple. If there is no difference, then all the amplifiers would be manufactured according to the same primitive and the cheapest circuit! The same applies to any product, be it a car, plane, phone, laptop, musical instruments, acoustic systems, or audio cables.I repeat once again that the problem is not with the product at all, but with the consumer’s taste, preferences, and most importantly, his bank account.

So where is the proof?
By the way, I've seen measurable differences between speaker cables so there is difference. Another key point is whether that measurable difference is audible or not. Based on double blind listening test results, the answer is no.
There are people who need evidence for everything. Even the most obvious things are that the sun is shining, and rain is made up of water. Apparently marketing tricks were created specifically for them. Just listen and compare the medieval violin with the one sold at the nearest music store. Medieval even sounds twice as loud! I will be silent about the sound quality, since I have no evidence recorded by the notary.
I am glad that you understood the point by saying the opposite. For example, that compared high-end amplifiers can have different frequency characteristics, but why, for example, do the compared cables always have ideal frequency response?

Yes you? Do companies produce different products at different prices with the same characteristics? Here investors will be delighted with this news ...

And how short is it? For monoblocks, it can reach more than 3 meters. An audio cable is not a musical instrument, it does not extract sounds by itself ... but it works as part of a system.
If your audio system generates extraneous noise or even a signal outside the hearing range due to a bad cable, then from the point of view of stability this is even considered a malfunction.
