Solid copper 14 AWG cable

But one thing, most folks seem to mention is the skin effect of stranded cables, which can result in a grainier / livelier sound signature. which some might prefer.

Stranded conductors are used to reduce the increase in AC resistance due to skin effect in solid conductors.

Also is "proximity effect" in solid conductors when placed close together and carry an alternating current of any frequency.

That's the reason why power conductors you see hanging on the towers or under the ground are stranded. They are compacted and shaped to reduce the airgap inside. Stranded conductors have less skin and proximity effect.

When it goes to telecom frequencies solid conductors perform better and it is said the stranded conductors have 20 to 50% more attenuation.

What's the thickness of each strand? 12 or 10 AWG?

Nothing to do with the strand. Skin and proximity effects are just the electromagnetic effect of alternating current. Electron diameter is 0.1nm and 22awg is 0.65mm or 650000nm and 12 awg is 2.05mm.

Power cable or line conductors strand diameter can go from a fraction of a mm to several mm.

So any practical wire will have these effects and I believe you can't escape them.

I have observed the spare aluminium power cables they kept in TNEB office. It had 5 strands and each not lesser than 4 mm thickness. They are not insulated as they use to be a bare wire hanging on the post to deliver power to home.

They had other power cables which is thicker than this but I didn't happen to go near them.

Those are probably for distribution network in 415V to 11kV range. The conductors in use in India for EHV network go up to 500sq.mm effective area with stranded steel core strength and aluminium strands 51 of ~4 mm. They are named Moose. Each size has a name like Wolf, Squirrel, Elk, Camel, Rabbit etc.
