Your response helps very much.
WRT point 2) it was not so much the shouty sound, but a muddling, homogenisation, or compression of the presentation when the ‘speaker is reproducing many instruments at the same time, especially if some of the instruments are producing bass frequencies and others sustained midrange. An example might be a vocal becoming modulated or distorted when a bass instrument is active.
WRT point 3) I am not referring so much to the perceived size of the soundstage, but to the metaphoric head-in-a-vice requirement to hear the mids (& highs) that some full rangers require… If I move my head a centimetre left or right, is the perceived frequency balance going to change dramatically; beaming – maybe that is the word.
Apologies for my somewhat confusing descriptions, these personal aspects of music reproduction are difficult for me to communicate.
Thanks again.
