litz vs silver plated for power cord?

I use the following wire from Take Five Audio

https://www.takefiveaudio.com/products/1098-mil-spec-12-awg-silver-plated-copper-cryo-treated-green/

It's the best I have used to date - for all types of cables.

It was better than Furutech, DH Labs and Neotech

I've used the same type of wire of various gauges, with great success on Speaker, Interconnects, and power  cables

Hope that helps

strange, what is the military's use for silver plated cables?

anyway, an increase in HF sounds good if that means an increase in quality/resolution of HF too, and bass quality doesnt decrease.
