. The 16 fundamental IC 741 based op amp circuits presented here are not only interesting but also very amusing to build. Use these at the main listening position to see what frequencies are dropping out or being amplified in the sub 200hz area, then set the opposite on the PC software to counteract (once the frequency is set then you an play around with the gain (dB/volume) and Q value (sharpness of the peak) to get a flatter curve). As the quality of the system goes up, the need for this enhancement diminishes. This sounds different. If the tone controls are early on in the amp the controls with affect what the signal looks like that gets distorted.
