Features

The Class A fully discrete op-amp is designed for professional audio applications, meeting users' needs for low noise, low distortion, and high linearity without coloration.
Using a high-performance temperature-stabilized power supply independent current source. The independent current source will be locked at the optimum operating point regardless of supply voltage or temperature.
The current structure adopts 5 pairs of low-error SMD triodes with twin tubes, multiple precision triodes are paired, and the output uses 1 pair of medium power to amplify the current of the tubes. The noise is less than 500 nv/rms (2.9 nv√HZ) @20Khz, and the output current can be up to 65mA.
The overall sound field is wide and full, with distinct layers, clear mid-frequency brightness, high density, deep and flexible low-frequency dive, suitable for a variety of audio amplifiers.
