Over time I too have learned that some people, including my friends, really don't care to look at or understand measurements. They would rather read what random people on the internet say about how "musical" a certain speaker is, or how "great an amp sounds", even when measurements reveal such products are not competently designedI think that would fail. I've learned over the years that people who have developed a strong, albeit false, knowledge of how things work don't believe the truth when presented with evidence. Like my buddy who took over 5 visits with at least hour long listening sessions to realize that my rig made plain ol' CDs sound vastly superior to his multi-thousand dollar turntable setup when he's spent well over 30 years perfecting.
As a result, I've learned that I just have to pick my battles lol.
