This is the result of not using negative feedback! What happens when you apply negative feedback to control a gain stage, a pop or tic comes by (non-audio event) greatly exceeding the slew rate of the forward gain, thereby breaking the loop. What happens is that you now have an out of control loop which has to recover. This exaggerates a tic into a huge event. When non-feedback gain stages are used there is no loss of control. A tic is amplified as though it was an audio signal. You don't get the prolonged recovery period, during which no music flows. This is clearly reproducible in testing. Easy to ABX.
