Mundorf Silver Gold Hook up wire

Looking to replace the internal speaker wire from Xover to drivers ( Tweeter / Midrange ) with Mundorf Silver Gold and looking for feedback from anyone who has used this hook up wire or comparisons between the Mundorf and UP OCC Silver Gold and the differences not just one is better then the other but specifics on why.

Please keep this on topic and I don't need to hear from the camp that wire doesn't make a difference or Im wasting my time.

Thanks in advance for your comments.
