1. Swap Guide
1.1 Essence One
Change all the Op-Amps of the same types in the same slot. For example, if you
need to change DAC I/V (slot 1), you would need to change all the Op-Amps of
the same types in all slot 1. If you need to change DAC buffer (slot 2), you need
to change the Op-Amps of the same types in all slot 2.
An operational amplifier (Op-Amp) plays an important role in audio performance
and tonal style by creating distinct listening experiences. Catering to the needs of
audiophiles, Essence series and Xonar Xense streamline Op-Amp modifications
with easily-swappable Op-Amp sockets.
