That depends some cables sounds different and some not.
The Jitterbug depends on your gear, here I use the Jitterbug for my hifi-nerves, but I can't hear the difference.
Supra Excalibur on the other hand is a big, big improvement, on almost all gear I suppose.
It's a very big difference between Excalibur and the cheap white Supra High speed.
The Cheap is way warmer and lack abit detail.
Excalibur is detaljed in all register and have a wide soundstage.
It's silly to claim that this is placebo, it is consensus on the matter from folks who try cables.
Supra is Swedish. And you are from Sweden. Bias right there.
Just sayin
