ACA top is having 1x voltage gain (what's logical) , while AC current contribution to output current is ~ 33%

as Pa sez - make those source resistors as chain of small valued ones , then just change output taps

while having same voltage gain all the time , you'll change amount of upper part current contribution in output current , thus changing THD spectra

just change places of 0R47 and 0R68 resistors , and you have 20% instead of original 33%

Now I understand better to separate the voltage and the current contribution of the CCS!

Thanks!

I do the difference of the two values and put it always in in proportion to the lower value?

mathematics is choking me too often.....:
