The "right" cables really depends on the specific system (components, roon acoustics, etc) and particular taste of the listener. I have rarely experienced cables that seem to work well in most systems. The more extreme the capability of the cable in certain aspects of performance (e.g., "fast and detailed"), the worst that cable seems to be in a system where those qualities do not need to be boosted.
The closest thing I've heard to as a univerally "great" cable system (I heard it sound great in three completely different systems) involved NBS Black Label interconnects and speaker cables. Too bad these are extremely expensive.
I suppose another surprising experience involved speaker cables made by the turntable manufacturer Basis. I heard those swapped for XLO Limited cables in a friend's system. Inexplicably, the system sounded considerably louder and more dynamic (not subtle) with the Basis cables. In my system I also heard an increase in volume over the NBS cables I use, though in other respects the sound was not an improvement, in my opinion. Still, I am amazed at the subjective loudness increase given that all cables have extremely low resistance.
