Gustard is going to unveil its new DAC-X16 with Dual ES9068AS digital-to-analog conversion chips which supports MQA full decoding via USB. DAC-X16 is going for US$499.99. It is available for the 10% off pre-order now which means you can get this precious at $ 449.99, this discount will last till Nov 16,2020, all the orders will be dispatched at the end of this month.




ES9068AS is the latest SABRE series dual-channel audiophile audio DA chip launched by ESS in the United States. It is the follow-up model of the widely acclaimed ES9038Q2M. It can not only achieve the excellent performance of THD+n -120dB and DNR 128dBA, but also the world's first audio DA chip with built-in MQA hardware renderer function.


When equipped with ES9068AS, not only it supports MQA full decoding via USB, but also can directly process SPDIF and I2S input MQA first-order expanded digital audio signals. There is no need for X16 to add MQA-related identification and control circuits, so as to achieve as little interference as possible by external control signals when the DAC is working, and finally achieve the ideal MQA playback experience.




X16 comes equipped with a Intel's ALTERA's large high-speed CPLD logic array chip, 2 American ACCUSILICON femtosecond crystal oscillators, high-quality audio dedicated linear power supply that helps derive the excellent performance numbers from the Dual ES9068AS chips.


It has CSR8675 chip by Qualcomm that enables Bluetooth 5.0 and supports LDAC, AAC, SBC, APTX, APTX LL, APTX HD and other high-frequency encoding, LDAC can realize 24B/96K high code transmission, Bluetooth function can be turned off in the menu.

    THIS DAC IS AWESOME, for the price!
    In my setup, i play from ROON ROCK > Router > HQ Player > Allo Signature > X16..all devices on cabled 6E.
    Everything from library to TIDAL, I upscale to DSD512 with NOS activated on the X16
    I could do lots off big superlatives, But i wont take ur time..other than this DAC is fenorminal.
    Thnks from Denmark

    An excellent measurements results on ASR forum:

    Looks very promising. Can it output a fixed volume level for connecting it to a pre-amp? Will it support MQA via Roon?
