In my experence the larger speakers sound most like real instruments. The body/dynamics of many instruments just are not large enough on small speakers. The laws physics of make most speakers sound like miniture recreations of the event. This is fine but real life instruments have resonances and tonal charteristics much better served by larger transducers. I have just added Tannoy Westminsters Royals to my system and they sound the most true to life I have experenced. They may not be your cup of tea but try to audition some horn type speakers preferably with tube electronics. It is at least a learning experence worth a few minutes of your time. Hope this is of help if I understood your posted question.
