Phono stages with adjustable input capacitance

 

— the ability to change the input capacitance of the phono stage to adjust it to other components of the system — in this case, the pickup and connecting wires. Recall that, ideally, the total capacitance of the corrector and wires should be equal to the capacitance of the “head”, otherwise an unpleasant coloration and additional distortions may appear in the sound. Without adjusting the input capacitance, this match can be very difficult to achieve. This feature is especially relevant for working with MM cartridges.
