And to many readers flowery prose was easier to understand than the technical jargon. So the "romantic" reviewers felt justified in their writings, many readers understood it better (none of my friends who are into hi-fi really understand much of the technical aspect, and it's also difficult for me), and the manufacturers probably sold more equipment.
