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!

I love the solid core sound. I've listened to many many IC's and settled on solid core for my system.

Z, Which brand solid core? Compared to what else? How is it different from everything else you've tried?
