Class A very low distorion but not very efficent, may use medium power transistors at the output  no feedback! biaspoint may drift over temp. or time

0.6% THD is ok but far from perfect.

How do you know the THD is 0,9% ? Is there a way to mesure THD in EC ?

so to get this right, you buffer the output and pass it thru an filter ? and the resulting sinal is the THD ?
