I’m convinced by @rodman99999 and his article he pointed me to that cables do make a difference in a measurable way. So you all have convinced me! See I wasn’t a troll after all. Thanks.
You believe "up till now" based on an article not on experience.
I imagine there is a difference between audio engineers and audiophiles when it comes to listening to music.
Audio engineers or audio reviewrs could prefer an amplifier such as the Benchmark AHB2, which is neutral very detailed, but dull and lifeless. It exceeds in accurately playing the source fed into it.
An audiophile prefers musical amplifiers over analytical ones. Many use tubes to induce second harmonics into the music. So for me, if my system could improve on Anthony Hopkins’s voice by introducing some harmonics I would be very happy with that.
