Incidentally, the Mirage OM-5 developed by Andrew, states:

We strongly advise that you resist the temptation to play the OM series to their full capabilities or experiment with critical placement and listening until they have been properly broken in. This process should last approximately 50 to 100 hours of music playback.This can be done efficiently and effectively by putting your compact disc player onRepeat mode, while playing a CD with a wide dynamic range at normal listening levels.
