An operational amplier (op-amp) plays an important role in audio performance

and tonal style by creating a distinct listening experience. Catering to the needs

of audiophiles, the Essence series streamlines op-amp modications with easily­swappable op-amp sockets.

if you need to change DAC I/V, replace the op-amp with a DAC I/V op-amp in
slot 1. If you need to change SE LPF, you need to replace the op-amp with the
same type of op-amp in slot 2.
