L1387DAC 8X 2026 Coaxial Optical Fiber USB Bluetooth R2R NOS Audio Decoder Full-featured HiFi Decoder (Silvery Panel)

Introduction:
- L1387DAC 8X 2026 is a HiFi decoder that is completely optimized for sound quality. Adopting for Philips' traditional TDA13878 chips in parallel, this chip is the same as the renowned TDA1541 and has a very similar style. Its overall listening experience is warm and moist, with a strong sense of air and analog charm, and is highly infectious in music. Abandoning the flashy DSD encoding of modern chips and completely optimizing for PCM.
- Using 8 TDA1387 chips in parallel not only has the significance of constant stop surface for sound density and dynamics, but also fundamentally solves the problem of insufficient output current of the 1387 chip.
- This machine uses three sealed transformers, providing independent linear stabilized power supply for the left and right channels of the digital and analog parts. A total of 7 channels separate stabilized power supplies completely separate each link inside the decoder, making the sound very pure.
- The input of the traditional R2R structure Nos decoder on this machine avoids jitter problems from a more fundamental perspective, restoring the original purity of the sound.
- The circuits of this machine are completed using traditional 5534 HiFi operational amplifiers. After multiple comparisons by the designer, it was found that only this classic operational amplifier can fully interpret this classic Philips sound. At the same time, the PCB has operational amplifier sockets, which are convenient for users to replace according to their preferences.
