In the US FM system the audio modulation "pre-emphasis is 75 micro seconds, with a corresponding 75 micro second de-emphasis in FM radios/tuners. This improves the overall S/N ratio.

However, that improvement in signal to noise ratio comes at the expense of reduced high frequency headroom. So it is a tradeoff.
 
Is there any differences between 50us vs 75us pre-emphasis for audio quality or it i just different because reasons?

Something I've wondered as well.
