- NCX10 stereo audio DAC
- HiFi wireless Bluetooth 5.0 CSR8675
- Support for APTX HD audio transmission
- UK digital structure scheme
- Full function remote control
- Italian daughter card
- Support DSD 64-128-256-512
- PCM supports 32bit 384K. Four-layer immersion gold circuit design
- AK4118 receiver chip
- TPA 6120 professional headphone amplifier
- Bluetooth 5.0 chip. Faster and more stable transmission. Bluetooth 10 meters + transmission distance, supporting for APTX-HD transmission protocol, APTX-LL low delay technology
- AK4499 DAC Chip: AK4499 four-channel DAC chip supports 32bit / 768kHz PCM and 22.4MHz DSD native decoding, provides 6Vrms balanced and 3Vrms unbalanced output power; signal-to-noise ratio: 124 unbalanced/ 125dB balanced ; Crosstalk: -138 unbalanced / -144dB balanced; THD + N total harmonic distortion: 0.0005% unbalanced / 0.0004% balanced @1KHz
- Use eight MUSES02 operational amplifiers
- Adopt Italian USB daughter card digital interface. It is recognized that the effect is better than that for XMOS. Support: 44.1kz, 48kz, 88.2kz, 96kz, 176.4kz, 192kz, 352.8kz, 384kzi2s 32bit or dsd64, dsd128, dsd256, dsd512
- Programmable logic chip can realize functions such as clock synchronization. Two American femtosecond clocks make the regenerated signal more accurate, lower jitter, more details and more real.
- Adopt AK4118AEQ chip with better sound in the industry as SPDIF signal demodulation, make coaxial, optical fiber, AES balanced input sound better
- The operating system uses STM32F 103 micro-controller, which makes the operating system more stable
- The amp part is a combination of MUSES 02 + 6120
- The core power supply is two imported power transformers. In addition to the three-level high-power linear rectification, an additional 19 LDO voltage stabilizing chips are used. The power supply of each channel of the digital and analog terminals of the whole machine is independently separated. We have undergone seven optimizations and rigorous electrical performance tests on the current circuit structure to truly achieve mutual interference, mutual influence, and strong power.
- Sound quality upgrade: The new core decoding, with a unique design structure, allows us to open our ears to explore new listening experience.
- Function upgrade: five levels of brightness adjustment of high-definition large screen, all content at a glance. Electronic filtering, vivid images combined with each style of appreciation experience. Fully in-line op-amp design to meet the HiFi needs of different music users.
- Material upgrade: 4 layers of immersed gold PCB circuit board, carrying a new architectural scheme, imported audio components, 1: 1 material ratio of all imported machinery, passing manual inspection.
- Tablet/mobile phone decoder application: For Apple's Lightning interface iPad and iPhone, it supports for connection via Apple's Lightning to USB camera converter”. For Android tablets and mobile phones, it can be connected to the decoder through  OTG cable, turning users' device into dial and get a better sound effect than the internal decoding of the machine through the decoder.
