Here the author explains why our hearing is so complex and our ears can be more sensitive to nuances than you think!
I am not disagreeing or agreeing with him. This is not to malign the author as I know this forum is very hostile to subjective opinions. Just to welcome discussion around this topic.
Summary of the video:

Summary of the video:
- First he goes on to explain the biology of listening, the whole auditory science. The boring part
- Then he goes on to explain why we can't completely rely on frequency response and distortion characteristics. For e.g. a system that has extra capacitance (holds the signal an extra 2 microseconds), will still have perfect freq response and distortion, but it will sound worse.
- Speed of transistors in the system matter, responsiveness of driver matter, all which doesn't show in freq response graphs
- Cables matter for timing performance (our ears are sensitive to few microseconds)
- Feedback loops in SMSL and Topping products help produce great measurements but those loops have to introduce more smearing depending on how fast the circuit is. He doesn't say all Topping or SMSL products are not enjoyable, just some of them, and that's why hearing is important.
- What we hear depends on the level, content, structure and history of audio signal. Tone based or sinus based measurements dont capture that. I have asbsolutely no idea what this means
- In general, timing and jitter performance is very important which dont show in measurements
