I've had some success with using an Anker Astro3E USB battery with a few phones using USB Audio Recorder Pro. Using a USB HDD split power cable to connect my Dacport LX to the battery and to my Galaxy Nexus, the battery provides full power to my Dacport LX which is exactly what I wanted! I tried this with my Galaxy S III and to my surprise the battery actually charged the S III while providing power to the Dacport LX as well. Cool! I wonder if that's a hardware or kernel feature..?
 
 
It should be a hardware feature and a USB driver feature supporting the Accessory Charger Adapter or ACA described in the USB Battery Charging Specification.

The ACA allows the Galaxy S III to be charged while communicating with a USB peripheral like a USB DAC when an external power source is connected to the USB peripheral and the Galaxy S III.

Anyone feel Neutron player has better sound quality through usb dac compared to poweramp? I am using Venturecraft Go Dap X with Note 2. No settings in Neutron player seems to make a huge difference.

i prefer Neutrons sound sig over power amp, especially direct volume control is much better(note 2).Unlike most people, I like the ui too!

I decided to quit using usb dac for now, can't find a nice interconnect, like jpapertowels my cable connector got bent within a couple of days. I also found the playback kinda spotty, sometimes it started playing through the speakers, kinda embarrassing! Moving over to digizoid for now, gonna come back to dacs when I can find a nice interconnect. Any suggestions would be appreciated!

I use Venturecraft Go Dap X. It takes straight microusb to microusb connection. Never had any hiss or mishaps.

NOTE 2 and HTC One X Plus owners.... I found after searching that this phone supports USB-DAC with the TouchWiz ROM.  Do any of you know if the AOSP ROM's like AOKP and CyanogenMod also support USB-DAC for this phone (without a patch)?
 
I'm getting frustrated with the lack of support on the Galaxy S3 AOSP ROM's.

can you give me a link to a HDD cable that fits your description.  i tried one of the dual USB cables and it may have been powering my dac/amp (not sure if i could figure out how to tell), but the charge idiciator showed it was not charging my T-Mo S3.
 
Thanks!

Anyone know of a standalone app that has cross fading? I have a player that supports it but I want some effects that'll work with Netflix and web content. Thanks!

Did you mean cross feeding? Neutron does that, well at least it has cross feeding setting.

Not that I'm aware of, being a Sony it should have USB OTG/host support, in which case worst case scenario should be that USB audio works via USB Audio Recorder.
