    very interested in this new gear, basically I'm done with USB but USB is still by far the most convenient input

    Is there a homepage for it ?

    I read through this a few days ago, it seems they will launch with 200 units in China only, before international distribution.
    I would order, but the HDMI i2s output does not match Audio-GD.
    I had the previous Gustard DDC and Kingwa changed my DAC at the time to match..
    We need find some photos of the finished product.. I am on the road currently but will return Sunday for the holiday week, and will have access to my full-time Chinese language search translator then :information_desk_person:

    Can it do dsd1024 out from i2s ? Pcm 768KHz?

    The specs seem still very preliminary:
    Highest support for PCM 32bit/768khz and DSD512, with support for DOP and native DSD.

    I cant find the specifications of this ES chip...if the chip is able to do it, the firmware will more likely to be. Though pcm 768khz is good

    my concern for these interfaces is the software.... it can be difficult to sync seamlessly with streamer/pc to dac as most chifi companies just punch out the hardware with no support there after

    Anybody try it yet?

    Seems to me it just started shipping, but I noticed on the Shenzhen Audio site that someone asked if the HDMI i2s pinout can be reconfigured and the answer was positive, see quote below..
    "It is possible to change I2S pins via software."

    I ordered one and they shipped to me last night.
    Will have direct comparison with SU-1 and DIO XLR on Dante protocol :)

    I2S should be configurable by soft, which is great idea. But most I am interested is SQ. Dedicated audio controller instead of standard one...

    Look forward to hear from your review. If it has a DC power input, would be even better so a LPS can be used.

    Based on available pictures no DC input. But no problem to make it if necessary.

    The matter of fact power supply design look very simple. Transformer, rectifying diodes, two caps + 5 pin Linear Technology VR (probably same as used in X20). Too simple...

    There is something mentioned in the q&a on shenzenaudio’s page as to the hdmi pinout can be configured through sw:


    Hi Pavel, 1. U16 can compatible with Holo Spring. 2. It is possible to change I2S pins via software. 3. U16 can compatibility with Linux (no drivers needed). Thank you!
