Pat highlights the importance of coherence to musicality and how one can sacrifice and live without stellar resolution to achieve higher musicality.
@carlos269 In his first post he seems to not be saying that at all. I agree with most of what he said there.
@antigrunge2 has it right.
How do you gauge and measure sound reproduction systems’ truthfulness to the source? What is the standard for analyzing, assessing, and scoring the fidelity to the source of home audio systems?
The best way is to make a recording yourself. That way you know how its supposed to sound. Its not as hard as you might think; to have a good recording system you can take into the field isn't expensive compared to what home high end audio systems cost these days. The main expense is the microphones.
BTW I don't take YT videos seriously. There are too many unknowns (the microphones, what sort of recorder use and the compression algorithms of the site itself). Many people simply use iPhones or the like, which have built in compression and limiting, and really don't sound right. I've used mine to record my band many times so we can woodshed material, but those recordings don't sound at all like the actual band.
Live MUSIC listen at near field position normally is not " relaxed " and and sometimes could be brigthness and even harshness, example:listening a horn/trumpet or sax alto .
@rauliruegas Certainly! We're on the same page. I'm just pointing out that a good system doesn't sound bright and harsh all the time to also be detailed. It is simply what the music is. So if the music demands brashness, its right there and if the music is relaxed the system is too.
