Yep, I learned decades ago that if someone is happy with the sound of two tin cans and some string, there is little chance of convincing them that your system is any better.
I think you’re right.
Bass heavy low resolution high distortion systems probably outsell audiophile systems by a factor of 100 to 1.
If not more.
’No highs no lows’ never bothered with accuracy but Amar Bose himself was left swimming in a sea of cash as a result of his careful crowd pleasing algorithms.
Accurate playback is not only extremely difficult to deliver, it’s not even on most people’s radar.
