i would appreciate is someone could teach me how to read / look out for "2nd order distortion" i heard they are what makes tube amps more pleasurable to the ear , but how do i tell if i look off a THD graph ?

like ... which spike is it ? how to tell if there is more of it ?

is it the width of the spike or the height of the spike ?

Thanks in advance !
