Sometimes I hear a difference when replacing a power cord with another, sometimes I don’t. I sell the cable that don’t bring anything better to my system. I keep the one that does. Then repeat.
There are times where the difference is right off the bat, to the point of being wowed. There are times where the difference is subtle, if any. It takes many trials, and over the years as the system evolves. It’s fun.
If you never ever found any difference with your new multiple cables you have bought, there is a possibility you are buying the wrong cables. It's a possibility. I admit, it is difficult to determine what cable WILL make a difference good for you and what consists an upgrade from your current cable. It can only be found by trial and error.
One thing that I recommend you do, after getting a cable that does make a difference to you, regardless of the scale, is listen to your system with your new (better) cable for a week. Maybe just a good weekend. Then switch to the old cable. Are you missing anything? Then you will know.
