This board utilizes a high-quality linear power supply paired with an optimized inverting amplifier circuit. When combined with a well-designed operational amplifier, it becomes an excellent pre-amplifier with low distortion, low noise, and comprehensive sound quality in terms of layering, detail, dynamics, and delay. The pre-amplifier provides the sound, while the power amplifier delivers the power, offering better impedance matching and thrust for the amplifier.
1. The double-sided immersion gold PCB has lower conductive resistance, superior sound quality, and an impressive appearance.
2. It is a fully DC circuit, with a flat frequency response from 0-100KZ, extended tonal range, and excellent detail preservation.
3. High-quality regulated power supply, utilizing linear regulator ONLM317LM337, ELNA filter capacitor, and Brown-Shen Black Gold decoupling.
4. The fully gold-plated IC socket facilitates easy replacement of ICs.
5. All resistors are sourced from Germany's non-inductive VIS cylindrical resistors, delivering superior sound quality compared to DALE.
6. It can be paired with an all-aluminum alloy shielding shell to reduce noise and create a quieter background.
7. With its compact size, the board can be directly fixed to the chassis panel by relying on the screws of the potentiometer.
