Most of us don't have technical background, I'm no exception. But I like to see what is inside a component. If I see a neat layout with quality parts it gives me certain feeling of "trust" with regard to both the product and the manufacturer. But I also know that just nice "cosmetics" and cool looks can be deceptive. OTOH some components don't have this neat interior but they are very good in reproducing music (= very musical). For example some of the point-to-point wired tube amplifiers (from Supratek and Atmasphere). Especially the Supratek units have very messy looking interiors.
