    So I tested it out. When playing a video via VLC Player using USB input; there is a slight delay in sound, as if a few milliseconds behind.
    When using Optical input, there is no such delay. Playing youtube the delay in USB seems less apparent compared to playing a video file on the computer, however when played via Optical there is no sound delay.

    I dont have any videogames installed on my computer right now! I'll have to try another time, though i suspect the same may be true for videogames as well.

    I haven't tried Coaxial or AES yet, however I suspect this delay is due to something going on with the USB implementation.
    Optical works with no apparent sound delay.

    Thanks for checking that! It sounds like a minor issue at worst. I may end up using the X26 with a DDC, probably the U16 or SU-6, so hopefully that will resolve the issue altogether.

    My dirty little secret is that I game using a $20 pair of earbuds plugged into an Xbox One controller. lol

    Lmao this is an outrage!
    Also I recommend the Matrix Audio X-SPDIF 2 USB Converter with iPower Low Noise DC Power Supply - including International Travel Adapters by iFi Audio (5V), works really well

    I have tried X26 for one whole week.

    The USB input of X26 is not as good as U16 i2S output to X26. I found problem above 192k with USB in, while I2s in via U16 has no problem all frequency (version 1.41).

    I have also compared it with Teac NT 505 and Audio-gd R7. It cannot beat both of them.

    End up I returned the X26 to the reseller.

    From my test for one week, the X26 is not so good.
    This is a comparison with TEAC NT505 and Audio-gd Reference 1.
    They both beat it.

    Run it for 300h first and don't listen at all. Then compare with other DACs. Other way it make no sense.

    Is it good for X26 or bad for Terminator?..

    It's good for X26, I think. It's the real progress in sound quality engineering for delta-sigma chips (so, they can sound analog-like now) and for much lower money.

    The DAC was borrowed from the reseller and it was run in for more than 1000 hours, the test is make sense.

    They are only selling at about US$1000 from Taobao.
