Do speaker cables need a burn in period?

Nonoise,
I still don't think you understand.  When you compare two cables side by side, it's a relative thing.  No need to remember what a "chime" sounds like.  You just need to know relatively how two cables sound with respect to the chime. 

If a person can't tell the difference from listening to something side by side, then there is no point of going any further.  Is that person you?
Are you saying you are incapable of listening to something side by side and cannot tell the difference?  This is the basis of your logic.  How sad.

Admittedly with the lack of seriousness in the thread, combined with many of the weird things claimed in the audiophile domain,  we can get in to a Poe's Law situation.  That said...

The same goes for fine, tonally textured base compared to one note base that can be introduced by an inferior cable.

May I ask (just in case you were serious):  How in the world do you think a cable could cause "one note bass?"   

(That is a cable that wasn't flat out defective).

"One note bass" can be "caused" by any component, not just cables.  Cables are filters when it comes right down to it and affect the sound just like any active components.

If Nonoise is serious enough, maybe he can come up with a definition of "One note bass".

Allegory. 🤔🐍💩

If what you mean by flat out defective, it doesn’t need to be that to mess with the signal. I’ve lots of cables laying around of many types and each one sounds different.

Some are close sounding in most areas and some vary a lot. Do you think that a 30 something gauge, single silver wire IC in a basically air dielectric can’t sound demonstrably different form a run of the mill, copper stranded Blue Jeans IC?

Where’s my Barolo?

And Andy2, you’re arguing the same point of view I am but stubbornly limiting yourself to just your way of seeing things. Step back and take a breath. But, if it’s the last word you need to have, then by all means, you can have it.

I see you posted whilst I typed so allow me another dragon of yours to slay. Your stipulation about how components factor in has nothing to do with me as my observations are with equipment already broken in. They are a constant in all of this. Stop with the Red Herrings.

All the best,
Nonoise
