I mean music played with acoustic instruments when I say "live". Electric guitars, synthesizers are out of context for what I've said. One still needs to hear acoustic instruments in multiple acoustic venues to have the baseline I've mentioned.I think we are perhaps talking past one another? You’re talking about reproduction vs. production. I would agree with everything you say in the reproduction vain. I am talking about production and listening to electronically produced music live vs acoustic music live. Timbre becomes problematic if we are talking about a synthesizer. And then we have physically modeled software instruments, and even with something as “normal” as an electric guitar, we need to at a minimum include the amp/cabinet as part of the instrument (and really all the stomp boxes) all of which are essential user configurable timbre. With modern PA systems the limits are human hearing damage more than anything, so I don’t see acoustic having a DR edge there. Masking may or may not be an issue depending on the source, but that is dependent on space and not the production. Often enough, in contemporary music, one can think of the PA as the instrument and the “instruments” as ways of playing the PA. Amazing music can be produced both acoustically and electronically. Acoustic just isn’t always the source and electronic isn’t just reproduction.
