DETHONRAY HPAMP HA-2 16-600ohm HiFi Audiophile Portable IEM Headphone Amplifier AMP

Description

DETHONRAY is based on GEEK spirit, with the concept of focus, innovation and pursuit of perfection, and is committed to combining real and natural listening feeling with simple user experience. To achieve this goal, the team in the structure, electronics and acoustics are carefully designed and a large number of experiments, to ensure the stability of the product. In terms of software and electronic design, we insist on deep customization and innovation to ensure the real-time and integrity of audio data and finally bring unparalleled auditory experience to users.

The OP amplifier and emitter follower are used in the core of the amplifier. The design of the op amp is no longer in the black box, which overcomes the shortage of the output current of the op amp and the inability to realize the whole class A output. In addition, compared to a fully discrete component circuit, the circuit's front-end voltage amplification uses a mature op amp, which avoids the noise caused by not strictly transistor pairing and improves playability. Users can replace it on their own without using an op amp to adjust the amp sound quality and other performance. The amp is powered up in a full Class A working state. The back-end current amplifier circuit uses a push-pull emitter follower, and a constant current passes at all times. Make sure the amp is still working in full A when playing big dynamic songs. Avoid crossover distortion for Class AB amplifiers. In the bias voltage part, the circuit structure blue LED and double crystal tube are independently developed to make the last four audio power tubes in the optimal break-over state with the output impedance as low as 0.1 ohm. When playing songs, blue LED dark blue stable light also reflects the stability of the system and sound quality. PCB wiring is strictly based on single point grounding, so that the current circuit of different paths will not interfere with each other. The amplifying circuit is made up of wafer resistors with high precision and thermal stability, and the circuit capacitance is made up of two 680pF WIMA thin film capacitors. Ensure excellent performance and sound quality transparency. The OP amplifier adopt TI original high-end audio op amp OPA627 in the circuit, left and right channel with one.
