Hi Bob:

What you say is partially true, although I'm not sure who was going heavy on the EMT plates. The big 
problem with spot mics is you get what some people call "congestion" (muddy, clogged sound with 
reduced clarity) when large numbers of musicians are playing at once. The flip side is that spot 
mics can aid intelligability and increase the soundstage depth and width during single-section or 
solo parts. Kazdin's best work uses so many mics (as do some Philips recordings and, as I understand 
it, some DGG recordings) that the complex parts can be remixed with a completely artificial balance, 
and perhaps some EMT echo, to combat the congestion.

At my AES presentation, we heard both of the RCA Living Stereo recordings of the Boston 
Symphony/Munch doing "Daphnis." The earlier recording, made with fewer mics, has a more consistent 
soundstage (to my ears) going from ppp to fff, but you lose clarity on the chorus because it's 
situated behind the orchestra and the setup is just 2-4 overall-pickup mics. In the 1961 recording 
(which won a Grammy), you hear the chorus (with its own 3-mic pickup) in much greater detail, plus 
the individual voices in the back rows of the orchestra, but when everyone is going, the soundstage 
collapses to the center somewhat. Kazdin's 1975 production (which also won a Grammy) doesn't have 
this problem, but some in the audience really didn't like what  they perceived as a fake soundstage 
and unnatural instrumental balance.

It may be that you either want to use a whole bunch of mics and create the producer's idea of an 
orchestral balance and dynamics, or you use very few mics (say, 3 spaced omnis) and let the 
conductor control balance and dynamics but place those mics in a "sweet spot plain" (which is of 
course a production since no person could have three ears floating in a plain above and behind the 
conductor, nor would those three ears have a presence peak that you're using the retail clarity at 
that distance) so as to get detail and focus as well as a consistent soundstage. To my ears, there's 
a legitimate beef about "congestion" during complex or loud parts of the score if you land somewhere 
in the middle and use something like a handful of mics to a dozen mics depending on the size of the
