I can’t quite be sure that I hear anything but minor tonal differences.
That’s the trick the ear is good at. Timing of transient function in the intermixing of harmonics... sorting out those intermixing bits. The high frequency extension may not all be there but the timing skills in harmonic intermixing is still there and will not really ever leave you. You are ’getting it’ just fine.
Running that incredibly complex ’tied to the world’s finest supercomputer’ (a human brain-fact) signal’s equation backward, reveals that the ear- brain’s analytical function FAR EXCEEDS the digital system’s resolution. Any extant or projected system to be.
Training the ear brain is another matter altogether and is also tied to the given various and individual Ear-Q of the given person. We are all different and we have dumb/slow ear-brains vs smart/fast ear-brains. It’s a physicality thing, it runs the range and gamut like all other human capacities as seen across the potential human ranges of skills in subjects.
There’s a bit more to it than that, but the next point is that you will get ’windmill tilting’ on the forums that is equivalent to a small group of individuals who don’t understand the complexity and the breadth of the subject. A small group... who angrily weigh in on it and thus tilt the given impressions of the situation to being that ’everyone’ seems to think such open and competent analysis of the scenario (analysis, orientation, direction and science which fits the data!) ----is crazy.
The reality is that they are a tiny minority of the population of people who could have and have read the given posts. Look at the number of views vs the number of angry deriding posters and you’ll quickly realize you are dealing with a very vocal tiny minority of detractors. The vast sea of viewers and readers are silent, as they pick no bone with the given analysis.
The science of what I’m saying is all out there and it is rarely shared by the electronic and audio oriented competent, as this is a part of their lore and intelligence - as tied to putting bread on the table. They owe the vociferous detractors exactly squat.
