Your comment is very cynical. Manufacturer manufacture things to sell… professional reviewers identify a fatiguing piece of equipment and would point it out… resulting in poor sales… however:
Inexpensive audio equipment can be fatiguing… those built to minimize cost of parts.
Some combinations of otherwise not fatiguing components can be fatiguing.
Many people turn on their analytical skills and listen for detail and crispness long before they understand how to hear a noice floor and high frequency hash… which causes fatigue. So they buy highly detailed but fatiguing components.
Folks that like to hear detail… and I think we all start that way, do not recognize when the musicality is striped from a component (rhythm and pace). Without it, you end up listening to the system and not the music. After the, “oh wow, I can hear a violinist move his foot.”… listening is not interesting. Systems that fail to produce music are exceedingly easy to assemble. All components must work together synergistically.
Systems designed to reproduce music tend to be pretty expensive.
