How do you know when a stereo sounds good?


When do you know your system is pleasing to listen to? How do you conclusively prove to yourself that your system sounds good to you? How do you determine that you enjoy listening to music through your stereo? Do you have a suite of measurements that removes all shadow of a doubt that you are getting good sound, sound that you enjoy? Please share.
