Later he told me that he thought his Alvarez and his Martin were the only guitars he would ever need, but now he is thinking that he needs another guitar, and that is going to be a Taylor.
Sound is a very complex thing, and with enough time, any part of it can be measured. But a good human ear with a sound mind can pick thing out in real time, faster than a team of engineers can.
That said, regarding ear training, some musicians can listen to to the beginning of a song and tell you the notes, and cords. While others may not have learned the name of the tones, they hear, and can identify the song buy those few tones. They may very well be hearing every thing, but just not trained to the same level.
I find the same with TVs. The more i look at them, the more i say to myself, "I vastly prefer the reds, purples, and detail of this cheaper set to that expensive one. And it is a Zenith!" and so on, and so on. Never knew TV difference could be so drastic. Sound IS distinctive to each person. That said, old school Cerwin Vega Home Theatre speakers (remember them?) are going to be SUPERIOR to cheap, light, pine box Optimus speakers with 10 watts.
Same with Oil, except that some oil -sucks- 90% is FINE and the rest has High Fe issues.
And some have books of proof that that is OK, and some say "No thanks, MY oil doesnt have Fe."
And both are correct.
If one is utilizing a $25 dollar Used Oil Analysis then the Fe count is misleading at best and you cannot base any oil decision on it. Short and sweet is the Fe count from a $25 UOA only counts certain size particles. You could have a report say you have Fe of 125ppm and your are fine. You could also have one that tells you the sample had 12ppm and your engine could be in big trouble as the analysis only counted certain sizes of Fe particles and missed the fine particles that reflect your motor is grinding itself to death.
