Speaker design, KenjiT and others.

After following these threads for a long time the common theme seems to be that there is no perfect speaker to reproduce sound. What I find a bit ironic in these discussions is that so much sound that we hear comes from speakers. For example pretty much any electronic sound you have heard before has come from a speaker of some kind. Pretty much any live show you have been to has either been supplemented by or sent to you via speakers. So what is this elusive experience that KenjiT claims may or may not exist?
Is it also like this? Most of what we see today is not driven by the sun but by light bulbs or a light emitting device. Yes there is really bad lighting in some places but when lighting is excellent are we really that  troubled by it not being like the sun?
