[Elecraft] KX3 - audio distortion after level 30

[Johnny Siu]

Hello elecrafters,
 
I fully understand that audio from the internal speaker of KX3 could be distorted at high level say >30.  However, even I plug in an external self-power speaker, the audio is still distorted if I set the AF level at say >30.
 
Apparently, the audio distortion is not only due to the small speaker but also caused by the internal audio amplifier within KX3.
 
Is my observation normal?  I am NOT complaining anything but just want to make sure that my radio is without fault.
 
Thanks for your help in advance.

TNX & 73,
