9038S Hi-Res Audio USB DAC Headphone Amplifier ES9038Q2M DAC Suitable For Apple Cellphones

9038S Hi-Res Audio USB DAC Headphone Amplifier ES9038Q2M DAC Suitable For Apple Cellphones

Features:
- This decoding headphone amplifier adopts ES9038Q2M and SABRE9601K powerful decoding chip and headphone amplifier chip
- ES9038Q2M is a new generation of high-performance low-power DAC chip, using 32bit architecture for HyperStream II. With extremely high signal-to-noise ratio dynamic range and extremely low harmonic distortion, providing extraordinary music quality
- SABRE9601K has the industry's highest performance independent headphone driver, which is widely used in portable devices with audiophile sound quality, high headphone thrust and extremely low distortion. Suitable for headphones, earplugs, big earphones, etc.
- The decoder adopts a player-like architecture, which is a master control + decoder chip + op amp design, with master control for ARM, ES9038Q2M and 9601K op amp. Innovatively adopts the core MCU for ARM Cortex-M4 as the main control and USB communication interface, featuring high performance and low power consumption. The decoder supports UAC2.0 standard, the sampling rate is up to PCM 384K 32bit, and hard decoding DSD128 (DOP)
- Reasonable design and premium components. LP5907 very low noise LDO is used to filter  DAC power supply. And audiophile chip CBB capacitors for Panasonic and tantalum capacitors for AVX are used to decouple DAC power supply. The amp part uses audiophile patch polyester film capacitors for Panasonic to filter, and uses a low-temperature drift resistor with an accuracy of one-thousandth (0.1%) to ensure extremely high matching accuracy and ultra-low common mode noise. While almost all other products on the market use low-cost MLCC and low-precision high-temperature drift resistors
- The decoder uses a silicon crystal oscillator with an innovative architecture of MEMS resonators, with extremely high stability and ultra-low phase noise, extremely low temperature drift over the entire temperature range, and phase jitter as low as 500 femtoseconds. The high-performance and high-stability silicon crystal oscillator makes the decoder's sound field wide and realistic, with clear intermediate and high frequency levels, and clear and pleasant sound
- Made of 8 strands of single crystal copper silver-plated wire, an adapter cable is used to connect a mobile phone and the decoder, which improves low-frequency dive and high-frequency extension performance of the decoder
- Good compatibility. Supports for most Android phones or iPhones on the market. Support for system windows10 above 1703, Android 5.0 above, iOS13.0 above. It can be used as a desktop notebook sound card. It is plug-and-play and driver-free for Win10. Not support for Win7, Win8, XP old systems or MAC OS systems
- Supports non-exclusive playing APPs such as for NetEase Cloud Music and Kugou Music, and supports exclusive USB output from those for Haiby Music and ViperHiFi players
