December 2013 Mid-Level DAC Comparison - Page 19

I will soon have a Fiio X3 with line out capabilities that I could try with the DACs.  However... the focus of this test is sound comparisons using my computer's USB or Optical outputs.  If I have time to try the phone or the X3 I will, but recognize that I might have as many as 14 DACs to test over a few weeks, and time is going to be very tight.  Please don't be disappointed if I can't get to the phone test.

Check the manual and you will see.
Not sure about android devices.

It uses a cable like this. I'll buy it for you if you can do the tests :-D

Then again if memory serves you need to have a custom Kernel for this to work. All depends on if your phone is rooted and if you can install a custom Kernel without wasting too much of your time Lol.

My phone is not rooted.  It uses standard android 4.1.1.  I have no interest in doing anything that would risk bricking the phone.  I also will not have any time to waste trying to install something more complicated than an app.  If we can make this work within these limitations I would be willing to try it briefly with each DAC.  Otherwise, I'm not going to be able to do it... Sorry.

Lol still found some for under 1400 even those days :P

I have tried Android phone + OTG cable with Anedio D2, but no luck. I used a special app, have limited usb DAC support. Didn't try the custom kernel way, that method should have better compatibility.

I would make you my travel agent if I actually wanted to make this trip.  But I really would rather stay home and do this DAC testing.

Can you tell us what exact model of phone you have. Ideally your phone is on DanBa's list at http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/3510#post_10013742 he updates this list regularly, thanks to contributed information from testers. 

 

We don't want to ask you to root your phone. I'm pretty sure most of the advantages of rooting, you can get the same by simply installing a stand alone android app called Universal Audio Recorder Pro. It costs $5.71. A USB OTG cable (a micro-usb male end to plug into the phone, and a standard original sized USB female on the other end, plus 2 pins tied together inside the cable) is even less. People here are happy to donate those minor costs, just let us know. If your phone is not on the list, we might even be able to come up with a phone to lend you!

 

You will see Universal Audio Recorder Pro mentioned frequently in http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/ It is an okay partial solution, far better than nothing. Many phones, and many DACs, can be resurrected and use USB OTG with this software. It makes things work in the all-too-common situation where the manufacturer does have hardware in their DAC or phone that is happy to use USB OTG, but they were too lazy or (willfully) ignorant to include a device code or a driver to support it.

My phone is a Motorola Atrix HD.  It doesn't appear to be on the list. 

 

At this point the issue isn't the money -- we're talking <$10.  I'm willing to do the phone testing if I have the time.  Given the large and growing number of DACs in the field, I'm likely to be willing to put at most only a few minutes into testing for phone compatibility, i.e., enough to check to see whether a song or two will play on each DAC without hiccups.  Is that enough to satisfy the crew, or would I have to do more extensive testing?
