I have not read the whole thread-so forgive me if this has been already covered.
I guess it comes down to what one considers "perfect".
If "perfect" means that you can't tell the difference between a speaker reproducing a signal and the original signal-consider this.
Let's assume the rest of the chain is "perfect"-mic-recording medium-playback electronics and you have a loudspeaker that has a single source as the reproducer and a totally flat amplitude and phase response.
Let's take a couple of different instruments and have them play the same freq/note-a trumpet- a flute- a violin and a electric guitar.
The problem starts in that each of these instruments produces the same freq-but in different ways. so the polar pattern of each instrument is different. Yet the loudspeaker will have a single polar pattern-that probably is not anything like any of the instruments.
So the "sound" in the room (as it bounces off of different surfaces-due to the different polar patterns) will be different. So it simply cannot be "perfect" or a totally accurate reproducer-even if everything is "perfect"-it is not the same.
I agree that good quality headphones are the best bet-at least to reproduce what the mic originally heard-if for no other reason that they remove the listeners room from the equation,
