does nordast silver wirong/munforg capacitors

Make a difference within a speaker. There is a company that makes a special edition speaker with these add ons. They claim that adding nordast silver inner wirong and munforg silver caps makes a noticeable difference in the speakers. Thoughts?
Sure it will make a difference. The question is whether or not you will like the difference. By the way, it's Nordost and Mundorf.
