Hello, James.

This is not going to get you where you want to go. Wire is NOT a significant source of white noise in speaker systems.

For example, it can be calculated that ten feet of #20 AWG copper delivering 0.1 watt to a speaker load of 3.2 ohms will have its white noise 170 dB below signal level. That noise level just isn't going to be detectable.

Sadly, there are some sharks out there who, desiring to line their pockets, will con you with such incredible nonsense that their gold-plated-latinum (remember Star Trek) or whatever plugs and cables and all will give you a signal to noise advantage of some kind, but all such claims are rubbish.

Your white noise problems lie elsewhere and searching out the cause(s) may be a real challenge.

Can you provide design details of your equipment, by e-mail if need be?
