    Headphone output, disnoise at  45 V PP output level into a 50 ohm load 

 
The THD+N is below 0.0015 % in the whole audio range. The measured THD+N result is very close to linear from  
20 Hz - 20 kHz. 
The noise contribution of the circuit at 45 V PP output level can be ignored. The circuit noise corresponds to a level of 
approx. 0.0002 %. Thus it can be seen that the graph mainly represents the distortion of the circuit.
