Solid core OFC vs stranded OCC copper

Why is my feeling that cable geometry, quality and treatment of wire, insulation and sheath materials matter the most. Also i would prefer to use solid core in a tubed system with horns and stranded on everything else. OCC, CCC, DUCC wires are definitely better sounding than OFC, but still cable construction remains important. Also depends on the connecting component.
