What would be highly educational for your own understanding is do listening tests with various amounts and types of distortion.i have some problems in keeping the THD very low (that is my obsession actually) I like that rare feeling of having a direct connection from the source to the speakers with nothing in between
Therefore a circuit with extremely low THD+noise is mandatory
The program 'distort' is highly educational.
It will teach you that better than 0.01% is not something anyone needs and might cure your obsession that low distortion is mandatory.
