@nonoise and @tantejuut That's what I have been posting here. If it is a subtle difference, then yes, my senses can be wrong. If it is a DRAMATIC difference, not only can my friends with golden hearing, my very educated hearing but also totally equipment uninterested friends and family members can hear the differences. I invite friends over and they exclaim how wonderful the music sounds (meaning reproduced). If it weren't for time limits, they would stay all day (2-3 hours is usual). Covid killed 1.5 years of friends coming over).
To a few posters today, everything I say is anecdotal and has no relevance because I didn't do blind A/B/X testing to determine the measured differences. Is that what this hobby (obsession for listening to music) is about? Maybe it is for some but not for the overwhelming majority of music listeners who are overwhelmingly not audiophiles either.
Now I think I will begin another forum concerning manufacturers supplying measurements and testing. WHY DON'T THEY?
