In your case it should be pretty simple - use well recorded piano music that you know well and ask yourself which system or change gets closer to the sound of a real piano in a real room
in my case And given the types of music I am most experienced with I use a variety of rather sparsely recorded folk music and look for system changes that get closer to the experience of real musicians in real space.
Listening for gross frequency response issues or the top and bottom of the range is besides the point if the system is messing up the small details
