    This is normal.. it's just like using WASAPI out w/ your PC and still being able to control the volume of the digital output.  keep your S4's volume at 100%.

    Now that is good news. It solves a couple challenges on my PC setup and should work with my HTC One and Asus Transformer tablet (crosses fingers). Sweet! Thanks for the heads up.

    Can someone please help me build a cart on amazon with what I need to use an amp / dac for my HTC one I'm not sure what usb otg cable to get or which dac amp to get, should I get the old e7 or the new e7k or whatever it is, I would like to keep the budget under 100$ if possible , if the sound quality won't be better I'm willing to spend a little more but not too much.

    Also forgot to mention I use only iems. My collection consists of "hf3's, x10i's, re-400's, tdk ba-200's, ue500's, e10's, gr02 BE's, s4's".

    Thanks :thumbup:

    I have been following this thread for a while and it seems to be a constantly evolving technology. I have an Xperia TL, and recently purchased a Clip Zip. Will Xperia>OTG>DAC/ provide a significantly better source for my E12 and modded T50RPs than the Clip Zip? I listen to FLAC CD rips. Thanks, satwilson

    Update on Sola/USB OTG Power Consumption Error:
    I think I have a faint clue as to why a cheap USB DAC inserted between Xperia Sola and a USB Device may solve the Power Consumption Error.
    I checked Windows Device Manager properties/Power tab for USB devices connected to my laptop, and here are the findings:
    1) A USB Flash Drive, that was rejected by Sola if plugged straight into the OTG cable:
    I know it's cyrillic, but the highlighted item is Mass Storage Device, and it claims it needs 500mA. 
    2) Another USB Flash drive, that was accepted and mounted by Sola, plugged directly to USB OTG:
    As you can see, the USB Mass Storage Device claims it needs only 200mA!!! Which means that Sola is willing to provide 200mA, but not 500mA. I guess the threshold is somewhere between these two values, but I have no way to tell the exact value.
    3) RSA Predator - rejected by Sola if plugged directly into USB OTG:
    The highlighted item says USB Composite Device (which is how RSA Predator reports itself to the host PC), and (unfortunately) it claims it needs 500mA of current. I know for sure that this is not true: Ray Samuels, while not going into specific details, told me that the Predator's USB power consumption is "far less than 100mA", and I have no reasons not to believe him. The Predator only uses USB to power the DAC cirquit, the entire amp section is powered by the built-in Lithium battery. And this is a very sad thing, because not only it reduces Predator's compatibility with power-avarious android devices, but I also think this is one of the reasons why it is incompatible with Apple CCK, because it calls the same error message: "the device consumes too much power". Which it does not in reality...
    And finally, the icing on the cake: 3$ generic USB hub!
    Bingo!!! The highlighted item says... well, you see what it says, it's in English :) But look at the right column value: 0!!! The device tells the host that it needs no current at all!!!
    This brought me to an emperical, not science-backed conclusion that a USB hub (or at least certain types of USB hubs) is not transparent for Android USB OTG host device, such as Xperia Sola, and, in case it reports 0mA power reqiuirements, you can plug a coffee machine into it, and still have it accepted by your phone.
    Disclaimer: a coffee machine was a joke. And if you burn something plugging things all over the place after reading this post - don't hold me responsible! :)

    How about a HiFiMeDIY Sabre USB DAC with some headphones driving capability?
    HTC One > digital USB audio out >> USB OTG cable >> HiFiMeDIY Sabre USB DAC/"amp" >> IEM

    Dr. Bott T3 USB 2.0 hub:
    "iOS 4 changed the power limits of the USB DACs via camera connection kit, i.e. broke things.  With iOS 4 you can use a Dr. Botts "T3" portable hub to fool the iPad into thinking it is using a powered hub, and then you can use the DAC fully portable without power."

    Hi everyone, a newbie here but had been lurking around for a long time in head fi :p
    Firstly, thanks to those who contribute to this great thread! I was researching for a reasonably priced, high performance portable player for some time, from Sansa Clip+ to iBasso DX100 (ya it's out of my reasonably price range) to Sony Walkman Z/F series, and I finally stumbled upon this thread. I think using a source, in this case an Android based device, that outputs digital signal is a really good move as this allows flexibility in setting up one's portable or even home rig. Anyway, please keep up the good work guys!
    Danba, I came across this post by Sony Support in their forum, think it might help? It was posted recently, Jun 20, 2013.
    I think in short, all the Sony devices listed here can be used with USB Audio Recorder? For official support, the Xperia Z, ZL and Tablet Z allows direct USB to DAC, and you can play songs with native player or players like poweramp?

    Don't make my mistake though, buddy! :) bear in mind two things: first, UARP requires at least 800x480 screen resolution. Otherwise the app will simply refuse to install. See my Xpera Go "no go" post http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/2700#post_9647443

    Second, don't forget the OTG power consumption error problem that Xperias have. Again, see some of my posts here recently.

    Thanks for your warning notes hummer! I was looking at Xperia V till I saw the problems you faced. Hope you can get them work out soon. By the way, do you intend to try custom ROM for your Sola? I was thinking, maybe a custom USB driver might help in your case? Maybe DanBa or someone who knows more can help. [​IMG]

    Would that dac be better than say a fiio e7 or e17?
