Hi Brooke, Any sound coming from the wires directly is probably negligible. But the vi= bration is going to result in electrical losses and also distortion. Whethe= r that is what I noticed or is measurable is what I'll try to find out. First I'll have to find some single strand wire similar to what I'd had bef= ore.
