I don't think I have ever seen the issue of old (older) age that we all are living, and how that affects what we hear, or think we hesr? I have been in this game for a long time, back to the Sansui and Fisher days. I have had my hearing test done at work every year for 44 years. There has been a gradual decline in my hearing. I know some is from the loud music, cars, shooting guns, and of course the work environment. The getting older is also a part of that, but I don't see anyone addressing that here when talking about what they hear from their systems. I believe you reach a point where the differences that you think you hear, are pretty minute. To each his own. I don't know how cables can be truely tested, without have them on a true A/B test switch, where you flip from one cable to another. Better audio shops used to alwsys have their better speakers set up so that you could sit and A/B them instantly on the same music. That way always got me to the best sounding spesker, IMO, that I could afford at that time. I did once have a shop loan me three speakers for a home two week demo in my own home, so that was good for me to do. I just hope all of the people here don't get too old the hear these improvements in their systems.
