I'd be curious to see if you took cable A which looked cheap, ie not a super custom logo ridden cable, and a expensive, thick, beutiful to hold and look at cable and did a comparison. But in reality the nicer looking cable was a crap Chineese made cable but looked good and the cheap, un assuming cable made with "high end internals", would you choose the better looking cable if you thought it not only looked better but cost more?
My guess is that we tell ourselves the more expensive looking, feeling/costing cable sounds better. I'm not so convinced it does. But hay, if one has the means, and they need to spend some cash to spruce up their cans, well to each his own.
