Eigenklang, I'm working with the author of those essays on a revised version and a translation, but it will be some months before it is ready.
In the meantime maybe the most important thing to state plainly is that there is no one "best way" to record; it depends hugely on the acoustical circumstances as well as personal preferences.
There are many two-microphone stereo recording techniques which can give a natural-sounding pickup, but they aren't always effective when amplification is being used--you might get a wonderful recording of everything except the singer(s), for example. (Been there ...)
All in all, I'd say most people on this board seem to be continually experimenting and trying to get better and better all the time.
