This dual operational amplifier is made of fully discrete components, with original imported 14 pairs of twin transistors, 4 pairs of transistors, and 2 pairs of transistors
Amplify the current of the transistor with medium power. Strict manual screening and pairing of components on the upper and lower layers can achieve better results
To match, but due to handmade production, it requires a few days to make and ship.


Class A output (CL.ASS A OUTPUT) is 15MA, with a maximum output of 65MA.
As a result, the overall sound quality is wide and full, the scene is grand, the layers are distinct, the mid-range is bright and clear, and the sound is dense



High frequency, deep diving and elastic at low frequencies.
High frequency performance: Excellent high-frequency resolution, relaxed and lively sound, suitable for string instruments such as violin, guitar, and harp
In terms of performance, transient control is excellent. Under better device driving, its dynamics and density perform better.



Mid frequency performance: The vocal performance is relatively full, with good analytical and imaging power, and the sound is smooth
The presentation details are natural, the hierarchy is clear, and the sound is clean.


Low frequency performance: Low frequency is sturdy, powerful, and faster, clean.


Note: The overall sound quality and style are generally similar, but there may be differences among different devices. Please be cautious if you mind. Thank you
