We could use two transistors for the VAS stage.
One is an emitter follower stage after the input stage feeding an ( ac) grounded emitter VAS transistor. The second would be a darlington VAS stage.
There is a difference in the distortion spectrum between the two . Is there any audible sonic difference between the two ? Any one prefered over the other ?
