Interconnects: solid or hollow core wire?


Which makes for better interconnects, all else being equal, single core or hollow core wire? Thin or thick gauge? Experience first, theory second!

Mrtennis - I think TNT Audio has some solid vs. stranded theory on the website and is the basis for some of their DIY cables.
I think the Audioquest theories make sense (although the science seems theoretical)...various sizes of solid conductors wound around each other....and in my audio system (as opposed maybe to my digestive system) it works really well. I assume the utter largeness and success of AQ as a company does engender what I see as seemingly unfounded criticism from the "audio-illuminati", but I use my ears for audio product testing and I actually LIKE the hard working Chinese people. Maybe I'll score some liquid nitrogen and freeze some cable and see what happens...I bet the dialectric cracks off along with the toe I spill the nitrogen on.
Agisthos, or use a ribbon, or a true hollow core like the previously mentioned Cogan Hall's.
does anyone think that the difference between stranded and solid core cable is easily recognized in a stereo system, assuming one is using either design for all cables ?

i think other variables can disguise the differences between stranded and solid core making it difficult to tell.
