Well its more than that. You see IF one uses recordings that are good facsimiles of live performances (ie. minimal miking and manipulation) and IF ones system with these recordings then delivers a sound that is quite close to what one hears live then it can be possible to give some indication of the accuracy of that system.If a system sounds good with a heavily studio processed recording, what can one say other than it sounds good or doesn't? This is because there is absolutely no reference for that recording. Who knows what it supposed to sound like? What is the native sound of an electric guitar or synthesizer? What does it sound like when compression and equalization have been applied. Or artificial reverb or chorus etc.? Unfortuneatly, this is exactly the kind of music many are using to determine the rightness of their systems. If that is all you listen to then that might be fine but if not then almost for sure your system can be dramatically improved upon.
Of course you can't compare DIRECTLY to live music unless you have a microphone piping live music through your speakers. Therefore, you need a valid approximation of natural acoustic music. The recordings that fit this bill the most closely are usually classical or some jazz recordings (especially live or minimalist recordings). The best is if you have some skill and make your own with good artists. Here is where JA (for example) has a distinct advantage over other reviewers and why I tend to take his reviews seriously. Now you KNOW what it should sound like as you were there and you have a record of the event. If it was done properly it should be a good facsimile of the live event. If played back through your system it is not giving a credible result then it is likely your system is not accurate somewhere along the way (probably starting with the speaker/room).
Now, I don't pretend that 100% accuracy can be achieved because the room alone will muck things up quite a lot. However; indicators of realism, low level resolution, microdynamics, lack of compression (from the system not the recording), transparency and natural timbre (this can be affected a lot by the room and the dispersion of the speaker into the room) can all be good giving a high degree of realism.
