Toole on why classical music studios prefer B&W speakers. Answer: the BBC dip?
In sound reproduction the final performance occurs in a recording control room or mastering room, both of which are dimensionally similar to domestic listening spaces.
Control rooms, by tradition, can be quite dead, but mastering rooms should be closer to typical playback environments, otherwise the "circle of confusion" becomes a factor - and that assumes that all parties employ timbrally neutral loudspeakers, which is not at all certain.
Equalization is part of that process. I agree that close mic'ed recordings can be problems, and if they are, it is an indication of differing tastes (or hearing performance) between the recording staff and the listener, or, equally likely, monitoring through spectrally colored loudspeakers - compensating errors.
Excessive brightness may also be the result of non-optimum mic placement.
This happens in concert performances with elevated mics picking up more high frequencies from violins than is heard in the audience.
There is a loudspeaker that is preferred for "classical" recordings by some experienced recording engineers - it has a sagging frequency response in the upper midrange/lower treble and makes the strings sound more natural.
This is a case of the monitor loudspeaker being deliberately incorporated into the recording - dumb.
Listeners will not hear what they heard unless they have the same idiosyncratic loudspeakers.
