I've actually had success both ways.
Initially for two years I tried a hodgepodge of different brand of cables without getting satisfying results. I then went to a single brand throughout my system including power cords and this worked very well.
A year later I got the upgrade bug and started to change out cables one at a time with different brands, and this worked great.
Eventually this led to outfitting my system with cables from a single manufacturer again and it was even better.
Just last week I received speaker cables from a maker different than the ones I'm using now.
So I guess the moral of the story is...
you can find success both ways as long as you find cables that work with your equipment. Or a combination of different cables that work together.
Sorry if I've confused you even more.
