there have been many adjectives mentioned so far that have been criticized as not useful. can anyone mention an adjective that is useful ?
most adjectives are ambiguous and do not have a predictable denotation. it is preferable to describe in a sentence what you are trying to say rather than using one word.
as an example, instead of using the word "bright", describe what you mean, namely an audible peak in the range 1000 to 3000 hz.
there are many descriptors which are imprecise that audiophiles consider useful, such as deep bass, wide and deep sounstage, richness, warmth, detail, resolution, etc. . while connotations may be perceived, there is much disgreement as to the definition of the aforementioned terms.
