Play lower and higher quality encodings through a decent size of sound system (2kW upwards) to discover what all those frequencies do

I think you need to lookup Nyquist/Shannon as already alluded to in this post. Plus it's about the quality of the playback, not how loud it is. Having said that, after spending a weekend in a field in Cambridge, in front of a speaker, my hearing is now pretty shot :)
