Cable septic

Okay, I’ve spent a fair amount on my dream system. Voxativ 9.87 system, very efficient speakers, Vocation 211 integrated, ps audio Directstream DAC and power station, etc. I’m using pretty basic cables, mostly what came with my equipment.  I still remember a magazine article where they AB tested high end cables neatly separated vs a mess of cheap crap.   The result, nobody heard a difference. So, flash forward, what cables will make a difference?  Brand and which component in order of benefit. Thank you!
