@snapsc- I would venture that if a system produces piano convincingly it ought to do most everything else well, given not only the range of the instrument, but the other demands placed on its reproduction-- dynamics, power, timing, harmonics, etc.
When I listen for evaluation purposes (as opposed to enjoyment), I try to use a range of different material, almost none of which is "audiophile"-- I don't mean that in a pejorative way, just that I don't want records that are known sonic spectaculars to find the weak points- i want to hear what a system can do "on average" since much of what I listen to was never released in audiophile quality issues though some recordings are still pretty killer. (and some aren't).
