XYBA: Line driver and buffer based on the Centaur input topology and parallel op-amp design

Two stages utilize a dual parallel op-amp design to reduce internal voltage noise by 3 dB per stage. This achieves a total noise floor of approximately -123 dBu, which sits well below the measurement floor of standard audio test equipment. Gain is switchable between two fixed settings: 10 dB and 17 dB. Designed as an always-on device for studio applications, pedalboards, guitar, bass, synthesizers, drum machines, and DAW sidechaining.
