The closest you will get is to go to RMAF (for a few years) and decide that for yourself, there simply cannot be that many folks who have had the time, or money, or inclination to have heard it all (and also be good listeners with critical faculties), in their home, with their electronics, etc. And then good luck trying to find any "authoritative" conclusion - it's just not like that. It gets all the more complicated when you take into account that the speaker is a very different creature depending on the amplifier and source driving it, let alone the room. And then, at the end of the day, if all that were possible, you would only know what that one person thought was best for them.
