Does anyone know how to properly test the output impedance of a cd player ,I have a sony dvp-9000es dvd/cd player and need the info to make a passive preamp

The manual does have some specs but I am not clear how to interpet the two specs,They are load impedance which it says (over 10 kilohms) and output level at (2 Vrms at 50 Kilohms).I thought it woud be best to test to get a acurate impedance value .Do you Know Which is right? 50 kilohms seems hight for a cd source impedance
