If you look up the UL spec, AWM cable is for the manufacture of appliances and machine tools. UL otherwise does not rate low voltage cable—including analog and digital audio cable. So, when a manufacturer is using AWM cable, they are using bulk industrial cable not specifically designed for audio. Like I said above, it’s not necessarily a sign that the cable will be bad, but it’s a sign the manufacturer is manufacturing its cable from stock with a different intended use. I’d rather purchase audio cables built from microphone cable stock. Not because they will sound different, but because they were specifically designed for audio applications, will measure better in terms of capacitance and reactance, and will be shielded in such a way to prevent interference with audio signal. All this instead of using whatever crap they had around in the warehouse, or whatever reason drove them to use AWM cable.
This makes sense. I prefer Belden Type E because they use it on marine helicopters, and I am sentimental about my days as a mechanic, but in lieu of that, I usually go with your philosophy. One exception is speaker wires, which I have decided to use extension cords for, because they are round, conduct well, are durable, and pliable.
As for Amazon Basics, I don't see the point. Just buy Monoprice premium if you want inexpensive Chinese audio cables.
If you want something good, get bespoke cables made from the best components, e.g. Periapt, WBC, BJC; Belden, Canare, Mogami, Amphenol, Neutrik, Switchcraft, which should be less than $80 each, or DIY. It is not rocket science.
