I agree with you re the piano and the remocal of intermodulation between notes "distorting" the piano sound. I think we can both say "Let's keep the piano distorted!" with a certain amount of glee :-) Actually I play guitar and it has the same sounding board "problem".I guess the problem is how to create a reproducer which can reproduce the original sound, "distortion" and all, without adding another layer of that sort of distortion in itself, due to its own method of operation. If we could achieve that, I wonder how we would react to the sound since we're so used to the existing sort of speaker sound. I wonder whether we would embrace it enthusiastically or claim it as a new sort of colouration. Many people aren't really intimately familiar with the natural sound of acoustic musical instruments and might not recognise the change as being closer to the real sound. I also don't know how much we all make implicit allowance for the fact that we are listening to a recording in our own living room. I know damn well I can't fit a symphony orchestra in that space but I tweak a bit and comment on how much more "natural" the recording of the symphony sounds. I sometimes wonder what I'm really saying, but I don't know any better way to express my reaction to the change and basic shared assumptions like some of the ones involved in how we "hear" recordings can be the ultimate blind spot for all of us.
I don't think we have to worry about intermodulation in air movement too much. If we get the reproducer "right" so it accurately recreates the original pressure changes, the air movement should be identical - provided we listen at the same distance that the microphones were placed at. Given some microphone techniques that could be difficult - a need to be in two places at once, or even more :-). Imagine a new distortion - listening distance distortion caused by the fact that the relationship of wavelengths in the music to each other is different at your ears than it was at the mike. Ah the pleasures of ever-increasing improvements in reproduction - newer nits to argue about.
