As to the T-8's, I think the key here is bad recordings. What one may characterize as bright and harsh another may describe as "revealing" or unforgiving. The T-8's are widely recognized for their sweet midrange and faithful reproduction of the human voice. And this is how I feel about mine. And, as I am also finding with my T-8's, because they are so revealing, (if it is recorded hot, it can sound hot), the choice of associated equipment can pose a challenge.
Also, the case could be made that one man's tipped front end could be perceived by another as a lack of "bloom" in the upper mid/ low highs displayed by another speaker in a comparison test, finding this trait an unwelcome accretion to the source. Is that what YMMV means?
