"....better than the musician sounded in the room...."
I knew that would be contentious, but it's the truth for me, although maybe 'better' should be replaced with 'different'.
Why do we (I) close-mic all these instruments, if we want them to sound like they sound in the room?
Re. 70 same-make clarinets, let me make a less subtle example;
if I record a clarinet duet and on the first clarinet I use a pre that gives a 10dB peak at 300hz, and the other clarinet with a different pre that gives an -8dB dip at 400hz, that is not consistent.
The harmony would not balance at all.
However, if I use the first pre on both clarinets, the recording will be 10dB heavy at 300hz, but will be relatively and harmonically consistent.
The ear can live with a 300hz heavy recording, but it can't live with an unbalanced harmony.
This is the principle (although very exagerated).
And the principle follows for a duet between flute and clarinet, or piano and flute etc. And follows for pre-amps, mics and other colouring stages in the process.
If you scale the 10dB at 300hz down by 1000% you get into the realms of 'feel', which are no less real.
Not to mention that frequency response is only half the picture. We have to take saturation/compression/phase/etc characteristics into account too (among other things).
We know that hearing is a relative adaptive sense, and for the suspension of disbelief, relative continuity must be maintained.
We can be engaged by a black and white film from the 50's with very distorted sound, because we accept that the world (for the duration of the story) has no colour and is crackly sounding. But it must be maintained consistently throughout the film.
To sum up. The suspension of disbelief is of paramount importance, in my opinion. I can enjoy cartoons.
Maybe my recordings are cartoon, in their way.
I do appreciate that from an early age we are told that one mic does not do well on every source, and that the same is true of pre's, compressors, reverbs, etc. Fight it baby!
Also, Level - I'm not sure I quite understand the subtleties of your reply?
I'm drinking tea, with milk and sugar, of course, like all good englishmen do.
