Why Threshold S300 has unequal resistors in 1st stage emitters?

[Mark Johnson]

I found this schematic here on diyAudio; it seems to show that the Threshold S300 power amp had an input stage with 100 ohms in the left transistor's emitter leg, but 82 ohms in the right transistor's emitter leg. (red circle).

Does anyone have a theory about why this is a good idea?

that just shows that Pa even then cheated , fixin' THD spectra to his own liking



(OK, maybe having phase behavior as primary concern)
