People used sing-along and dance with audio music in 30s~70s. The audio industry and dealers talked about the natural sound always then. The musicality of hi-end audio was excellent then. Into 80s, the audio industry couldn’t complete the natural sound and gave up on the natural sound. I remember that a famous man said "hi-end audio has peaked and no more improvement from now" from early 90s. Since late 80s with Dolby surround sound, the audio industry turn the table to the sound technology and they don’t talk about the music nor musicality.
Say "Hello" repeat with below appear to be a nice video sounds. You’ll hear lots of speaker distortion. Right. Seems to be a nice sound without your "Hello" sound is, in fact, a bad dirty sound. There is no musicality from the sound like that.
The audio industry needs to understand how bad the current fake audio sound is and find real natural reproduction audio music.
