Xiangsheng just released in 2021 the latest DAC03 II/DAC-03B, still with PCM1794 chip, but add headphone output, and Bluetooth CSR8675 5.0 module ,
Black/ Silver USB option: the DAC is with standard SA9023 or TE7022L USB decoder(depend production periode, both suport 24bit /96khz sampling rater)
Black / Silver XMOS USB option: The DAC is with better XMOS XU208 USB decoder (suports 24bits / 192khz ampling rater)
Features:
Compatiblity of device OS of SA9023USB: almost of Windows , MAC, Android, Apple-phone(only with camera set) Compatiblity of device OS of XmosUSB: almost of Windows , MAC, Don't support phone/tablet device
This DAC has two stereo RCA outputs : Normal op-amp output OR tube buffer output . it's convenient with tube amp or transistor amp, to get different effects .
The main amplifier board with dual-panel design , production of fine .
The local digital and digital to analog conversion receiver using CIRRUS CS8416, and TI 's PCM1794A
Tube output module use Russian 6H3n tube, the sound is mellow. High voltage and filament are regulated DC power supply.
DAC has 3 OPA2604AU Op-amps:, manufactuer chage often the op-amp, so we can not make sure what op-amp extactly, but all are the same/very close quality/sound(confirm by XiangSheng manufacture)
The machine resistors, capacitors do not use SMD components , but are of high quality discrete component assembly fever , so the sound quality can be guaranteed. The machine uses a lot of fever components: the Japanese metal film resistors, Germany WIMA polypropylene capacitors, Suren capacitor , CBB subminiature metallized polypropylene capacitors, monolithic capacitors. Never use of polyester , tiles and other common components. Thus ensuring pure sound , high resolving power , small bass , a wide sound field and so on.
LED indicators for source inputs
The use of the superior performance of R-type transformerpower supply ( often used in high-level hifi equipment ) , although the cost ratio circular , square transformer greatly increased , but high efficiency, small magnetic leakage .
Digital and analog part of the independent power regulator rectifier filter to reduce interference
RCA output and coaxial plug are gold-plated to reduce contact resistance.
Realization of the functions of the machine adopts MCU control , channel status and the volume remember when the last shutdown
It use almost all HIFI level and high quality electronic components
With Bluetooth CSR8675 5.0 module
Headphone amplification output on front panel with TPA6120 amplification chip and CS3310 chip for volume control on front panel, by default the volume knob is just for control headphone output, it's not control for signal out
