A perfect example for me would be Harbeth. If this is what you like then more power to you, but please dont mistake these type of designs as accurate.
Bad example, I think. At least for certain models. The SuperHL5plus I owned was beautifully neutral-sounding. JA from Stereophile in measuring said it measured "superbly even" aside from a lively cabinet it measured "beyond reproach."
Stereonet sent it for extensive measurements and the result was what they deemed a combination of frequency extension and linearity that was to their memory "unprecedented."
Perhaps you are thinking of other Harbeth models? (Though I still find Harbeth to get tone "right" in a way that escapes many other speakers).
Anyway, not gonna say more on that as that's not the reason for this thread. Anyone can prefer what he prefers of course.
