Disclaimer I'm no audiophile, I just like to measure stuff

Feel lost when you sit around with your audiophile friends and they talk about this transistor gives you better high freq responce. Or this one gives you better mids. Or this chip amp has more warmth than that chip amp.
Im a guy who just likes to measure stuff. So have some doubts.
Its there a way to measure stuff like warmth of an amp,
As far as Im concerned and with the limited few amps I have put together. I like to just measure the output. In most cases so far I see that I have a flat response curve. i.e. feed it a 1 volt peak to peak signal from all freq from 20Hz to 20Khz. And Im happy when I see that the output curve out of the amp is flat. Sometimes Ill just do a Channel 1 - Channel 2. And if the curve is flat with no distortion call it a day.
Have read up as much as I can. And am still confused. When audiophiles are talking about differences in amps. Are they purely talking about stuff that can be measured or is there a component of stuff that cant be measured. Or am I just not measuring the right things the right way ?. Or is the magic in the imperfections which cant be measured ?.

You likely need to look at other measurement parameters, such as distortion, as well. An amp with flat frequency response could still have high distortion readings. Another area could be output impedance--into a purely resistive load, and amp could measure flat, but hang a speaker on that amp and all hell can break loose FR-wise.

Time resolution is plenty - no problem there either for our measurement systems. I dont believe one have to understand how it works - what is needed is to explore it's limits. That is black box characteristics. Knowing how it works can be interesting but absolutely not required to find the hearing limits.

Being able to explain a sound or noise is difficult. Getting on the same page when it comes to terminology is the key
to understanding the results from an objective or subjective view. There is plenty of information that will guide YOU
to a better understand of terms. Personally as an old HD mechanic I didn't have to explain noises. I just had to fix them
if I was lucky enough and someone else was paying attention 1000 miles from me.

Because some are in a business and some are hobbyist doesn't mean the problem doesn't exist about being able to
describe sound.

I can read an oscilloscope just fine, explaining what a scope pattern sounds like so another tech or hobbyist can
understand, LOL

I think it's one of the greatest obstacles in the history of man. How many languages are there?

I honestly think point and grunt was a better form of communication. Maybe an occasional whack with a club
or two. 😎
