Do speaker cables need a burn in period?

Virgin Morrow cables

"don't immediately suck and then magically become fabulous, although they do seem to improve a bit."  

Mine cost <10% of equivalent Morrows, and they DO immediately suck (uncertain about the magic to come). So I'm thinking maybe we get what we pay for and this thread is way out of my league. Thanks, folks!

That's almost as good as this video with all the cables in the wrong direction:

It’s perhaps not obvious to the casual observer 👀 but the power cord should be in the right direction, too. Actually, all wiring and cables including the digital cable and Ethernet cable and HDMI cable and of course fuses, should be in the right direction, too. 🔜 Even a stubborn mule can hear the difference. Yes, I realize this is supposedly a hot button topic 🥵 but the only debate is in the mind 🧠 of the pseudo-scientist. 🤔

As the little mice in Babe sing, that’s the way things are.
