Microprocessor with Quad Core structure
Using a high-speed quad-core 1.3G core processor and a FPGA , it can play PCM768 and DSD1024 master format music files, supports various formats such as DST/ISO/CUE , and has a strong adaptability that is unlikely to be replaced in the short term.
It can mount internal mSATA removable solid state disk , has a rear USB 3.0 interface , a hidden TF card interface on the panel.
It has infrared remote control , remote control via App , supports a NAS for playback.
With coaxial / optical / AES outputs , IIS can meet your HiFi audio source needs.
S5A integrates an AK4490 DAC converter , with RCA analog output with adjustable volume, up to 0.00042% distortion.
The patented structure of large FPGA + high-speed DDR memory combined with a proprietary audio algorithm used to reproduce low-jitter, pure digital signals, ensure top audio performance.
The FPGA operates with two clocks precise to the femtosecond and with very low jitter, thus increasing the overall intelligibility of all musical nuances.
Adopt custom circuit- specific digital power transformer , two groups of independent linear power supplies, let you get excellent dynamics.
The system cache + FPGA equipped with a large buffer form a secondary FIFO buffer, resulting in a purer output signal.
The output circuit adopts a full isolation transformer dedicated to digital , so that the digital output signal is always fully isolated, free from interference, and the sound quality can be as clean as possible.
The measured performance is excellent: -141dB at 24bit/1kHz , jitter 204.5Ps, the ideal near-end jitter curve, make the sound more real.
The S5A is equipped with an exclusive aune mobile application , which allows you to operate the machine via your mobile phone and manage your music files. It's fun and simple, easy and convenient.
