1. OPAMP Circuitry: The OPAMP uses TI original high-end audio OPAMP OPA627 in circuitry and the left and right each one. Compare with the discrete component circuitry, this headphone Amplifier uses mature OPAMP technology for voltage of the former amplification. This technology avoids noise from the transistor match difference and improve the playability. User can change different OPAMP for adjust amplifying circuitry timbre, performance and so on.
2. A full Class A Working Status: The rear current amplification circuitry uses Push–pull emitter follower, that has constant current pass constantly. To insure when the amplifying circuitry plays large dynamic music and it still works on full class A. It avoids the class AB amplifying circuitry crossover distortion.
3. Four Power Transistors: TND+N＜0.0004% (@1KHz RL=600Ω) and the output impedance under to 0.1Ω, driving stage add in four power transistors to drive easily market popular Headphones. Supports 16-600Ω impedance headphones.
4. High Precision, High Stability: The amplifying circuitry uses entire high precision, high stability wafer resistance and the loop capacitance uses two 680pF WIMA thin film capacitors to ensure excellent performance and timbre clearly. Usage time is 8 Hours.
5. Loop Noninterference: The PCB wiring is strict on the basis of single-point ground in order to the different routes current loop noninterference. The bias voltage unit is via independence R&D circuitry structure blue LED and geminate transistors.
