As I'm based in the Middle East, meaning asking about a micro USB OTG cable is an exercise in frustration resulting in my reliance upon Amazon.  I do not think the cable itself is bad; could you please leave your cable unplugged from the DAC and plug it into the Note 2 and tell me whether or not a "USB device connected" notification pops up?  Because that's the behaviour exhibited by my setup.  I'm also sure that the E07K is good as it pops right up on my Linux laptop.

 

If push comes to shove I'll attempt to upgrade the kernel to your recommendation.  While I don't have any problems configuring, building and installing kernels on Linux...I just wanted a phablet that worked.  Of course I want to run a DAC off it so that desire isn't set in stone.  Wondering if it's worth waiting for another stock kernel update or take the plunge of rooting and installing the new kernel.

sorry for the late reply :

yes connecting the DAC triggers a "USB device connected" (or something like this, as I have the UI in french) notification ; and for your later question, there is no settings to change to let the DAC work with the Galaxy Note 2 : as soon the DAC is connected, I open Neutron media player and the sound is routed to the device (no more Note 2 speaker sound), I have nothing to do.

Anyway I think akong has an older unit....you can get the cable from Toxiccable cause he's an authorised iBasso dealer for 5 dollars if I'm not wrong.

I actually did get the cable in the package, I just lost it :P 

I can't find the cable on Toxiccable's or iBasso's website, or anywhere else. Is there anywhere else I can get it?

It isn't listed on either site, you just need to PM Frank here on HF and let him know you're interested. You should know in advance that he is apparently swamped right now and might be a bit slow to respond (I was looking at buying one too and got lost in the shuffle, I think). Very highly thought of around here, just very busy, it seems. FYI.

Ok.

 

An update.  I have the international version (bought from Amazon and since it had a French manual I am assuming that it is a French model also...but obviously in English for me) and when connecting my OTG cable, with or without the cable being plugged into the E07K it states "USB connector connected".  Upon trying to play music with Neutron it skips to the 12 second mark and then keeps skipping forward 20 seconds per real time second.  I.E., one second in the real world has Neutron skipping from 0-12 second mark, 12-32 second mark, etc.  Funnily enough using the stock player does not result in a similar situation regarding the music skipping ahead, but still no sound is sent to the Fiio E07k.  Using the USB Recorder app it asks for permission to access the usb device and then plays the music through the DAP with no fanfare.  The big problem is that nearly all of my music is in 320 mp3 and it would be nice to listen to my movies if possible.

 

I've rooted my device and installed the 3.036-Perseus-alpha35 af@mintvm #1167 SMP PREEMPT Sat Apr 6 19:17:38 CEST 2013 kernel...and it's still the same issue.  I'm a bit at wits end here.

Frank actually list it in ebay for that cable.Try this link below.

Interesting!
So the iBasso D-Zero has two USB modes:
. bus-powered mode when the USB charging is enabled
. self-powered mode when the USB charging is disabled
 
How long does it take to drain your Android device with the bus-powered mode and with the self-powered mode?
 
A Galaxy S3 can play continuously during 7.5 hours while powering a bus-powered Graham Slee Bitzie USB DAC/amp.

http://www.ebay.com/itm/261184542392?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

 

17 bucks and it sounds pretty damn good for the price.

 

Watches well with the RSA shadow size wise and looks.

 

 

Thanks!

I''ll add the Muse Hifi USB DAC to the compatibility list on the next page 145 (i.e. page of the current list + 5: 140 + 5).
 
So far, there are 93 USB DAC reportedly working with the Galaxy S3.

You can use a standalone USB DAC along with a JDS C5 amp to bypass the Android device’s internal DAC & internal amp:
Android phone > digital USB audio out >> (external) USB DAC >> (external) JDS C5 amp >> headphones
 
The JDS C5 amp can also be used to bypass the iPhone’s internal amp:
iPhone + internal DAC > analog line out >> (external) JDS C5 amp >> headphones
 
 
The $109 iBasso D-Zero can be used as a standalone USB DAC as well as the $99 TCG U-SKIN.
May be the $15 Muse HiFi USB DAC mentioned by TekeRugburn and the $189 JDS C5 meet your $200 budget.
 
Also, there are some compatible C-Media chipset based USB DAC sticks for some dollars.
 
If you can exceed your budget, you could request "the ODAC in the C5 case from JDS.  A match made in Heaven, now the wait begins to replace my 4s with a Note 2 later this year when I am eligible for an upgrade".

I stand corrected! Thanks for the link!

 

Btw, in case anyone is looking to use the S3 w/ a USB DAC while charging, I picked up one of these from eBay and it works fine w/ my S3 and PCSTEP. It provides power to both, which is handy. I was hoping to be able to use it in conjunction with the Samsung dock, but it's a no-go. Makes for an awesome way to charge your phone and listen to music as you retire for the evening ;).

I have an odd quirk with a Razor HD>OTG cable>Fiio 07K>phones....Using USB Recorder app, I often have to fiddle. I get an audible signal but it is squeaky and distorted. If I keep stopping and starting the app, eventually the playlist plays properly and I get great sound. Any idea why this happens and a fix would be welcome...Both the USB recorder app and the Fiio device come with VERY substandard instructions.

I'd prefer not to be stacking components upon components.  I want something slim, quick to take out of my pocket or backpack (while in use) and the ability to make use of the amp foremost, DAC functionality second.  If I can get them both to work in the same unit later on (when and if I switch to a Galaxy) then I'll be happy with that outcome, but right now...I'm concerned about the amp working with both iPhone and then the Galaxy without having to change hardware when I do upgrade phones.

Get an Apex Glacier. Its the slimmest amp/dac.

does a couple mm really matter that much?

post #2142 of 5579

How about a VAMP VERZA?

To some people it does - that's why all the new smart phones have been getting slimmer at the cost of battery life :(

post #2144 of 5579

I see that both the Android compatible DACs (V-MODA VAMP VERZA, XDUOO XP-1) and the USB Audio Recorder PRO app supports nearly the same devices.

 

Other than that I hear that the requirements are:

  • USB Host (Basically almost every newer device can do this)
  • USB OTG Cable (Who worries about a cable?)

 

1. Basic problem is simply CONFIG_USB_AUDIO parameter set to false? Shouldn't a mod like CyanogenMod enable this?

2. V-MODA VAMP VERZA, XDUOO XP-1 are the only USB DACs to support the ADK interface in Jelly Bean, or why are these the only "Android-supported"-DACs ?

3. What exactly is the difference between the Verza, XDUOO and the other DACs? Why wouldn't any DAC be compatible through USB Audio in the linux kernel ?

 

I really wish to lift my Samsung Galaxy S2 sound quality, and I am ready to spend the money to make it sound good. But the Verza is too expensive for me and has few other outputs and inputs so I doubt the reuse for the crazy price. I simply can't trust XDUOO before they make an english website, god knows what will happen on warranty issues!

I don't think it is self-powered...

 

I think the charge switch makes the difference between:

 

- bus-powered mode with the charging circuit enabled

- bus-powered mode with the charging circuit disabled

 

Which would still mean a reduction in powerconsumption, but not as much as you'd hope for.

 

 

I don't have a D-Zero, but I do have a D2+ and switching charging on introduces quite a bit of noise, I think that's the main reason for the switch. 

 

I was planning on building another OTG cable soon, I'll check if the DAC works if I connect everything but the 5V from the DAC.

If it works, it really is self powered, if it doesn't than the charge switch is actually just that: a charge switch...

 

I'll get back to you on this :)
