In audio many people had no acoustics concepts or training, they think that all pertain and is explained by design of gear pieces be it tube or S.S. or class D or Class A etc or Vinyl versus Dac etc ...
But an audio stereo system work as a whole synergetically or not in three working dimensions : mechanical, electrical and acoustical...
Then even if design choices of each gear pieces matter for sure , it matter less at the end than the way we use each one of them in and for a system/room/ ears-brain ...
Because reviewers and marketing sell a piece of gear as a solution, people forget not only synergy necessities but they dont focus on the system as a whole and they dont focus on the ways( mechanical, electrical and acoustical) the system must be inserted in these working dimensions in a rightfull manner.
Then they use gross classification based on price tags : low fi, mid-fi, high fi. And they think that solutions are all costly and ready made.
There is five vocabulary in audio : electronical design concepts and vocabulary, audiophile threads language, musical concepts, acoustical vocabulary, psychoacoustical concepts ... We must learn how to hear and learn how to distinguish all these concepts in a concrete way.
