I have had the opportunity in the past to do blind comparisons as described here. Frankly, I couldn't tell the difference. Semi, what I would like to know is this: When does the gauge of wire have an effect? I noticed when I swapped the speaker wire on my car amp for a heavier pair, it seemed to play louder with less distortion. I don't think sonically it sounded any different - just louder. (Any yes the connections before were solid) I know that a heavier gauge will handle more current, but was this just my brain telling me it "must" be better?
