That's a good point but I would have been curious to see the PC World folks do the same study for speaker wires. Is wire size making that much difference? I'm aware of the electrical differences between different gauges of wires for example but could it be that there is no audible difference beyond a given gauge?
Maybe the quality gain curve is exponential; lots to be gained from (let's say) 20 gauge to 16 gauge but very little from 16 gauge to anything bigger?
