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.

@frank009 I’m quite content with what I have and am not looking to make any sonic differences to my system but rather I’m curious what others have perceived.

Common wisdom says the power cable, is the most transformative. Yet most people will purchase speaker cables first as their first cable acquisition. 

Analog cables for sure. Specific cables are gear dependent.  This is probably the general answer to your question. But if you are more specific about the gear application specific, you will be getting more useful recommendation.

@gkelly i own several headphone amps, both solid state and tubed. Years back I noticed a hum on an OTL headphone amp. The power cord was very basic, and I swapped that out with a diy Belden cable that was shielded. Problem solved -
