    No jitter in Wi-fi streaming : protocol uses buffers and interruptions, data are reclocked, like with asynchronous USB.

    Android phones and USB DACs

    320kbps is very close to lossless : blind test and results. A DAc like the HIFIMEDIY SABRE U2 ASYNCHRONOUS USB, 57$, will improve significantly the Moto G headphone output. But does it works with your phone without UAPP ?

    USB Audio Player PRO (UAPP): 24- and 32-bit playback, ubiquitous USB audio support for Android

    That's a hardware problem I think, may be a USB isolator .

    Improvements for Hibymusic in the audio file classification : If I choose "genre" and, for exemple "Jazz", it shows all jazz audio files by alphabetic order. Anyway to classify first by "genre" next " artist" next "album" and in the end title by album order ? the same in all classification... Ty

    you should have a look to the Hifimediy UX1 sabre DAC : it's a ESS9023 sabre DAC but it has got a SPDIF output (USB to spdif converter). The USB receiver is a Savitech SA9023 : this receiver works with UAPP player or Hibymusic player on a lot Android USB OTG device. Two Hifimediy USB DAC are...

    Hypex as2.100 needs Windows drivers to work USB audio so I think you'll need specific Android drivers. The DAC workings with Android uses standard USB audio driver classe1.

    Hibymusic works fine with a Hifimediy DAC U2 asynch. There is no analog volume control on the Hifimediy U2 async so it's a numeric control : I hope hibymusic works on 24 bits with the DAC. bug : -Volume keys are ok but don't work when the equalizer is on the screen. -When you open hibymusic...

    I have a Ainol novo spark 9 tablet with CM11 and Hibymusic working well with it. The Spark9 tablet doesn't have USB audio feature with stock rom. (tested with Hifimediy U2 async DAC and Hifimediy UD80 FDA amplifier : these two use the same USB receiver chip, a Savitech SA9023)   You need your...

      Nice  player  : working fine with ZTE V965 and Hifimediy U2 Asynchronous DAC. Working also with my Hifimediy UD80 FDA amplifier. 2 questions : - any way to use digital volume ?  -Hifimediy u2 DAC should works at 24 bits: if the file is 16 bits, is the USB transfert working in 24 bits ...

    That's not a DAC but a full digital amplifier : the Hifimediy UD80. "The HiFimeDIY UD80 is a true Digital PWM amplifier with no A/D conversion, no preamp or any analog signal path anywhere before the output stage. This makes a very direct link between the digital source and and the outputs...

    Android phones and USB DACs

    I'm just using the smartphone charger with a Y OTG USB cable like this one : I first connect the charger to 220V, other side to the Y cable and plug the phone (phone is charging). I connect the DAC to the Y cable and last, I open UAPP. But if the phone battery is ok (more than 50%), I don't...
