@captainactic you can audition many cables through *the cable company*.The reason they all sound different is because there are so many ways to alter the signal impedance,inductance,resistance,and capacitance.Everything from the connectors,the dielectric,the specific materials used,etc. change the sound.
Like bigkidz says altering the signal internally in the components themselves obviously changes the sound and it can be altered externally as well.
It can be fun to buy,sell,borrow cables to find the perfect compliment for your particular system.It can be frustrating sometimes - me:Wow!The midrange and bass are perfect with this ic!Uh,what happened to the cymbols?!Dammit!😂
