Jkalman - I'm curious to know what your sound reference is?
Krisjan,
I like acoustical material as well to give me an idea of how accurate a speaker sounds, especially since I have been playing instruments myself for over 18 years (~25 years if you include piano). I play electric as well as acoustic instruments, so I like to hear how that sounds too. The thing about "grain" and "dimension" though, or "lifelike" qualities to the sound. Those are characteristics you notice pretty easily when they are there, or not there, especially when the speakers aren't fooling you into thinking you are hearing the real thing and not just speaker output.
However, if you use studio produced rock/pop recordings as your reference, then anything goes because no one really knows how they should sound except the mixing engineer. Then the evaluations become entirely subjective.
Since every consumer recording is in some way put through a studio engineering process (as far as I am aware), including acoustic music, I don't think that is a practical statement, seeing as "every recording" is, as such, subject to your criticism. So no one "really knows" what any recording is "supposed" to sound like except the engineer who made the masters. You are still left with having to decide based on subjective preference, i.e. - what sounds more "real" to your ears. To my ears, the Wilsons sound more "real," than the Vandersteens.
Also, if you want to really replicate the experience of the engineer, you would need to use the exact speakers the engineer used, as well as his studio space, so you get the same acoustical environmental effects he was getting during the mastering. Unless he used Vandersteens during the mastering process, there is no way they will be accurate in terms of what the engineer was trying to portray, as every speaker is colored differently. I'm sure you can see what a dead end argument the whole thing becomes.
Lasty, you would need the engineers ears and brain as well, since we are each subject to perceptual differences that cause us to hear things a certain way dependent on our unique ear structures and brain processing.
