Most tests (except for frequency response) can also be carried out without measuring instruments, just by listening, and are therefore particularly well-suited for the ambitious music listener who wants to know how well his system deals with demanding signals under realistic conditions, and whether there is a need for repairs or improvements.
Tacet thanks Albrecht Krieger for his ideas and advice.
