    thanks for your input. i'm familiar with schiit- i have a gungnir in my home system.  but i'm looking to upgrade my portable rig, so they don't have the right product for that application.

    "In the second design, the external audio peripheral C can be designed for higher audio quality and greater power output without impacting the cost of the basic mass market Android device B. Yes, it is a more expensive design, but the cost is absorbed only by those who want it.
     
    Mobile devices are notorious for having high-density circuit boards, which can result in more opportunities for crosstalk that degrades adjacent analog signals. Digital communication is less susceptible to noise, so moving the DAC from the Android device A to an external circuit board C allows the final analog stages to be physically and electrically isolated from the dense and noisy circuit board, resulting in higher fidelity audio."

    Intentional 4G/3G/2G/WiFi/Bluetooth radio frequency emitters and receivers with a high electronic integration density within a very limited small volume like smartphones, i.e. small computing devices, should create a lot of EMI/RFI noises.

    AudioQuest demo pre-production JitterBug at CES 2015:
    https://www.facebook.com/audioquestexperience
    http://www.audiostream.com/content/audioquest-jitterbug
    http://www.digitalaudioreview.net/2015/01/audioquest-demo-pre-production-jitterbug-at-ces-2015/
     
    "... 
    So what the heck does AudioQuest’s JitterBug actually do?
     
    Three things: 1) it’s a line conditioner for the USB voltage bus; 2) it’s a signal filter for the USB data bus. In both instances it suppresses the electrical noise that comes pouring out of your computer and messes with your DAC’s super-sensitive circuits; 3) When introducing a demo of the JitterBug’s capabilities AudioQuest’s Steve Silberman explained that “it also attenuates the entire signal to remove parasitic resonances”.
     
    Putting it more simply, the JitterBug doesn’t re-clock the digital audio stream (as its name might suggest); it filters out USB nasties and lowers the amount of electrical noise travelling along your USB cable.
     
    If that makes no sense to you, look at the JitterBug as AudioQuest’s answer to the Schiit Wyrd (US$99) or the iFi Purifier (US$99). AudioQuest’s JitterBug halves the entry fee to US$49.
     
    The units used for this CES 2015 demo were all naked prototypes – the shell design is still to be finalised ..."

    It should be paticularly useful for USB DAC without noise filtering.

    Hi,
     
    I hope someone here can give me some advice.
     
    I have a Galaxy S4 running android 4.4.2 and I have had it working with the HiFiMeDIY android DAC and the Epiphany Acoustics EDAC (ODAC) no problem at all. I purchased an HRT Microstreamer, which I new was listed and discussed here to work with some android phones, but I cannot get it to work with my S4,
     
    I have tried Poweramp, Neutron player and USB Audio Player Pro to no avail.
     
    What happens is that when I press play there is no sound and the song progress bar plays to the end in maybe 3 seconds and goes to the next song. I have read some posts that other people have had this problem but never found a solution.
     
    I no it could be an OTG cable issue and I have ordered a new cable. It could be a power issue, but I do not want to order a usb power hub unless I am confident it will fix the problem.
     
    Has anyone had the same problem and solved it on any phone or with any DAC?
     
    Any advice is greatly appreciated.

    Maybe you have a buggy HRT microStreamer.
     
    Maybe you should PM to walkman_heart:

    "using my microstreamer and s4 has much better sq
    than microstreamer and laptop combo"

    Thank you so much @DanBa. I have got to get better at using the search facility.
    I have PM'd Walkman_heart in the hope that he can guide me in the right direction.

    Anyone hooked up a fiio x3 or ibasso dx50/90 to an android phone yet?
    Do either work as a DAC/amp for android?

    Look into the following compatibility lists:

    I just got my HRT microstreamer working with my stock 4.4.2 Samsung Galaxy S4. I had to install USB Audio Player Pro, enable android in the UAPP settings, and enable audio out in the phones Accessory settings. It works perfectly and is so loud. I also added the Cayin C5 amp to the setup and it is sweet indeed.

    This 1,800 yen / $14 app called Ne PLAYER is in Japanese only, no DSD support yet but the features are pretty cool

    ・FLAC(〜24bit/〜192kHz)
    ・WAV(〜24bit/〜192kHz)
    ・WMA(〜16bit/〜44.1kHz)
    ・MP3 / AAC / HE-AAC / Ogg(〜24bit/〜192kHz)
     
    Support for internal storage, SD card slot, and external storage via USB OTG. The cool thing is showing the rate of the file on the top as well as the rate that's reaching the USB DAC

    It looks great. I'm interested in it. Too bad everything's in Japanese.

    Is there anything else than HibyMusic, UAPP, and this one?

    Onkyo HF Player for Android with Hi-Res driver support cooming soon too. http://www.phileweb.com/sp/news/audio/201412/20/15346.html
     
  15. kawaivpc1

    Looks interesting. Their current Onkyo player supports FLAC but it will downsample everything above 88.2kHz.
    I can't read Japanese. Are they saying it will support DSD with high res USB driver?
