L1387A 8X Decoder 1969 Pure Class A Headphone Amplifier 8xTDA1387 HiFi DAC Replacement for TDA1541

Features:
- Fiber optic, coaxial, USB input; Line output, headphone output, a fully functional decoding headphone amplifier all-in-one machine.
- CLC filtering + two-stage voltage regulation + parallel voltage regulation, the cornerstone of decoding - power supply.
- MCU soft control digital receiver: The microcomputer dynamically optimizes parameters and adjusts the phase detector of the receiver chip (CS8416) to automatically adapt to the input bit rate and minimize jitter. Simultaneously achieve the cycle selection of input sources with a light touch button, which is aesthetically pleasing and high-end.
- Equipped with eight pieces of TDA1387, after multiple comparisons, the sound of TDA1387 is the closest to that of TDA1541 in the same industry. After parallel connection, the current driving capability of 1387 increases, fundamentally solving the gap in dynamics and density with TDA1541.
- The digital part has two series connected voltage regulators, the MCU and the receiving chip are powered independently to ensure minimal jitter.
- Three parallel voltage stabilizers are used to supply power to the analog DA chip and LPF respectively. The quality of parallel voltage stabilizers is much better than that of LM317 and so-called servo power supplies. The disadvantage is low efficiency, but it should be ignored in decoding such low current environments.
- Integrated with the classic 1969 pure A headphone amplifier, the pure A has some advantages such as warm sound, low distortion of maximum volume output, good damping, and perfect control.
- Perfect wiring, multi-level decoupling of digital and analog, strict differentiation.
