What type of cables make the most difference


What type of cables, in your subjective experience, makes the most difference? I’m not focusing on brands, but rather, on type, ie, speaker cables, power cables, analog interconnect, digital interconnect, and anything else I may have omitted. If you don’t think cables beyond a base level of competency makes a difference that’s fine too.

ANY TYPE CABLE DESIGNED AND MANUFACTURED BY HAND, using "solid core 7N OCC copper" (silver plating optional)

The answer is all of them. 
 

on high end audio setups. 
 

on mid fi setups cables differences usually can’t be heard. Have tried on mass market gear setups. Not enough detail and resolution to bring out differences. 

The most significant power cable in my system is the one plugged into my Audioquest Niagra 7000 power conditioner and the wall outlet.  I currently use an Audioquest Dragon HC power cable.  That cord is something, as well it should be considering its cost.  Since everything is plugged into the Niagara, it affects the sound of everything plugged into my system. 

Next, I find that cables carrying a signal makes the next biggest contribution, especially anything that plugs in from a source (DAC, turntable, reel to reel, etc) into the preamp.  I recently changed  the cable between my transport (Luxman D-03X) and my DAC (ARC DAC 9) when I replaced my trusty Kimber Black Orchid to a Synergistic Research Galileo SX; that was pretty significant jump; I also have to say the new (to me that is...) Kimber Select 1136 XLRs from preamp to mono maps was a nice jump also.
