D-3 Audiophile Hi-Fi Digital Decoding Player with ESS9039, Bluetooth 5.4 and Hardware DSD Decoding for Hard Drive Playback
The system of this product supports switching the display language to English.
Product Description
1. Dual Independent ESS DAC Chips for Enhanced Sound Performance
This player is equipped with two original ES9039Q2M decoding chips manufactured by ESS (USA). One chip drives the left channel and the other handles the right channel in parallel decoding architecture. It improves channel separation and restores richer audio details for better overall listening experience.
2. Four TI LME49720 Professional Op-Amps for Pure Sound
Four TI LME49720 op-amps are built into the unit, which are professional Hi-Fi grade components featured with low distortion, ultra-low noise and high slew rate. They are applied in the I/V conversion and LPF filter circuits to optimize signal conversion and minimize signal loss.
3. 2nd-Generation Discrete Linear Power Supply for Ultra-Clean Power
Clean power supply is fundamental to premium audio performance. The device adopts the second-generation discrete linear power supply that restricts power supply noise below 20uV. It delivers steady and noise-free power for digital processing, DAC decoding and analog output, reducing audio interference from the power source.
4. Audiophile-Grade Qualcomm QCC3084 Bluetooth Chip with Full Codec Support
Built with Qualcomm audiophile-grade QCC3084 Bluetooth chip, it supports multiple high-definition wireless audio codecs including LDAC, aptX-HD, aptX-Adaptive, aptX-LL, aptX, AAC and SBC, enabling high-fidelity wireless audio transmission.
5. Independent Monitor Headphone Jack with TI TPA6120A2 Amp Chip
An independent headphone monitoring port is available for instant lossless music playback. The built-in TI TPA6120A2 stereo headphone amplifier adopts current feedback architecture, offering 128dB signal-to-noise ratio, ultra-low output noise of 0.9uVrms and a slew rate of 1300V/μs, delivering studio-grade headphone amplification output.
6. Fully Balanced Differential Circuit without Coupling Capacitors
The whole machine adopts fully balanced circuit design with differential wiring throughout the entire signal path. Coupling capacitors are removed from analog outputs to avoid frequency attenuation caused by capacitor performance differences. Meanwhile, it delivers stronger load capacity to preserve complete original audio signals and achieve low-loss Hi-Fi high-fidelity playback.
7. USB Sound Card Function for High-Resolution Hardware Decoding
It features a built-in USB sound card function via USB 2.0 / USB-PC port, compatible with mobile phones, tablets and computers running iOS, Android and HarmonyOS systems. It supports hardware decoding of high-resolution audio sources up to DSD256 and PCM 384KHz/32bit when connected to computers or mobile devices as audio sources.
