@hilde45 after comparing a cable in my own system, when fortunate to do so, I like to try and take the same cable to a few different friend’s places and compare again with a completely different system and room setup. While it can seem to be a bit of a swag, it can be interesting to listen for characteristics that do carry over with the cable. It can be much more interesting and valuable when comparing on another transparent system.
I often read folks stating a cable should not have a sound. My thought is all cables can impact sound, and which ones impact the sound the least and let the music through is what I enjoy listening for. Some hear differences, while others don’t. Finding the "giant killers" at a lower cost has been another reason to evaluate different cable designs.
