Do speaker cables need a burn in period?

Never addressing what I actually said, Kaitty is nothing if not consistent in his predictably lame response. I was speaking specifically and obviously about my personal take on home audio based on many years of experience, but somehow Kaitty arbitrarily connects me to pro audio because I'm successfully professionally involved in that field as a live sound technician and mixer. However, pro audio provides sound for live music which is, in fact, an actually important force that is far more powerful and relevant than Kaitty's oft ridiculed and silly fraudulent tweak business, the general impact of which seems to be providing laughs for those inclined to check out his stuff. Perhaps it's a parody of tweaking, but more likely a scam. No offense, Kaitty.

Thanks for reminding me why I never read your posts.

I prefer cables isolated from floor on maple blocks/sticks, like Pro Gold on connectors,  never tried cryo.  always followed manufacturer on direction, current cables non-directional according to designer...

never tried fishing line

Your cable guy must not have gotten the memo. Also, nothing wrong with maple blocks but I don’t think they are doing much vibration wise since the maple blocks provide a clear path for vibration.
