Stranded vs singal core conductors and skin effect

Yea, Yea, I did a search. I did find similar topics, but I still don't know which solution is preferable. Many mega-buck cables utilize solid core. Is solid core a better solution (conductor, etc.)? Isn't it the geometry (twisting, braiding, etc.) that addresses the skin effect issues? Are there other scientific reasons for utilizing stranded wire vs singal core? I am really considering making some DIY speaker cables. If for no other reason, than just for kicks - sounds kind of fun. I have read up on so many different theories. I realize that inductance and resistance are extremely important factors, as well as capitance, and for whatever reason, it must be a challange to design a cable with extreamly low measurments in all three categories?? I don't really fully understand why. HOLD ON - I don't want a complete lesson here. I'm just seeking some input from the engineering-minded or the knowledgeable DIY community as to which type of wire offers the best conductivity (and other factors??) for designing a DIY speaker cable. Additionally, which geometry is the preferred method?

Trelja, So am I, an engineer, that is and an amateur cook. About tasting, it is easy to get people to think that there is a difference in the taste of different salts and inevitably those people do 'taste' a difference, when, unless the salt has been deliberatly doctored, there is no difference. So careful with analogies.

I have also learned that my ears-mind are also easily fooled and therefore not always reliable for detecting differences even when they are real, nevermind when they aren't real.

I do understand, however, the expression, 'perception is reality' and perhaps that that is what you mean.

Respectfully, Bob P.

My point, however, Trelja, was that all salt tastes the same, but people do think that they detect different tastes, because someone has convinced them that salt from the sea is different than salt from the inland salt caverns. Theoretically, perhaps, there is a difference, but practically, the level of salinity is so high that one could not taste the difference, if indeed there is one. same with the stranded skin effect on the sound of cables. Yes in theory, but no in practice.
