Both USB module and motherboard use Lint's lowest ripple output linear regulator chip in the world, which has been reduced from Texas 4.17uV used in the old version to 0.8uV unprecedented. Using AKM low-time-base error digital receiver chip and adding American SiTime low-phase noise clock, the time-base error is further reduced. Coaxial and AES input uses digital isolation transformer to isolate front-end noise.
All rectifier diodes have been changed from the 3A of the previous generation to the 10A model with high current and low loss. The capacity of the total filter capacitor is doubled compared with the previous generation, and the quality of the power supply is greatly improved. All PCB boards have been rearranged and routed. High voltage power supply of electronic tube increases voltage stabilization circuit, prolongs the life of electronic tube, and makes the power supply more pure.
The USB module uses the latest XMOS U208, which is twice as fast as the previous generation U8. USB module I2S output with digital isolation circuit to isolate the digital interference introduced by the computer.The USB module uses the American SiTime low phase noise clock, optional Crystek CCHD-575, CCHD-957 femtosecond clock. USB module provides external clock input. It can use 3.3V to output 22.5792 Mhz or 24.576 Mhz atomic clock or OCXO thermostat clock.
MCU MCU controller has been upgraded from 8 bits to 32 bits, and its operation speed has been increased 10 times. Digital isolation circuit is added between MCU MCU controller and main board DAC to avoid the interference of MCU to high precision DAC. Tube rectification, switch switching support 6.3V series and 5V series rectifiers 6Z5P, 6X5, 5AR4, GZ34, 5U4G, 274B, etc. All-electron tube output, supporting 6.3V and 12.6V series of signal amplifier tubes 6H6, 6H30, 6922, E88CC, 12AU7, etc.Upgrade the circuit of the earphone part, improve the sound quality, and add the function of automatic disconnection of the front-end output when inserting the earphone. High-power 150W and 100W double-loop transformers supply power independently, 100W is responsible for the digital part and 150W is responsible for the analog output.
Pure and high surplus power supply is sought. The world's first user-switched DAC chip and output coupling capacitor design.DAC chip modules can be continuously upgraded and replaced. A new type of DAC chip will be produced next year. We will introduce corresponding DAC modules for users to plug and upgrade themselves. Users can customize different timbre performance by changing different output coupling capacitors. MCU firmware Downloader is attached randomly.
Users can upgrade firmware to support more future DAC modules. Users can enjoy the latest DAC chips without switching. USB input supports PCM384Khz, DSD256 (AK4490), DSD512 (AK4497), DSD128 (ES9038Pro). RCA and true full balance XLR fixed level output with high and low level adjustment.
Independent RCA interface front-end output, and amplifier output interface.
