  • D70s 32bit/768k DSD512 DAC MQA Version
    The D70s can act as a preamp or a pure DAC. It has a built-in volume control function which can be adjusted from -99dB to 0dB. It is also possible to switch off volume completely. This keeps the output to maximum level so that it can be worked as a pure DAC.

    2x AK4497
    AK4497 is the flagship model in the AKM company. We use a full AK4497 for every channel in the D70s. This results in better channel separation and better specifications. THD+N has even exceeded the performance marked by the AK4497 datasheet.

    Bluetooth 5.0 LDAC transmission
    D70s has the certification of Hi-Res audio Wireless and LDAC. It uses CSR8675 chipset to support LDAC/AAC/SBC/APTX/APTX LL/APTX HD protocol. To get even better sound quality from Bluetooth, we abandon the built-in DAC of CSR8675 and connect it's digital signal to 2 x AK4497 to decode.

    DSD512 & PCM32bit 768kHz
    D70s uses the 2nd generation 16 core XMOS XU216 chip. USB supports up to PCM32bit 768kHz, DSD512 native and MQA decode. With the help of the customised Thesycon driver, your pc will have better performance on ASIO playback.

    AK4118 Receiver
    AK4118 is the lowest jitter S/PDIF receiver at present. It has good compatibility which is used to receive optical, coaxial, AES signals for D70s, support up to 24bit 192kHz.

    CPLD
    D70s applies the CPLD, focusing on the clock processing and signal optimisation. CPLD combines with the accusilicon femto-second to bring a lower jitter effect, while coordinates processing of digital signal optimisation to effectively improve signal quality and
    stability.
