Thank you so much for the information DanBa! This thread is so great and I am hopefully soon gonna try pairing my Galaxy S3(4G) with Leckerton UHA-6 mkii!

I've tried searching this thread but couldn't find the info on the following but would it be correct that for the Galaxy S3 if :-

1) non-OTG cable is used with something like the VentureCraft Go-DAP X, it's USB Audio-enabled Android mode
   - the VentureCraft Go-DAP X won't be draining or siphoning the battery off the Galaxy S3
2) OTG cable is used then it's USB Host-enabled Android mode
   - the USB DAC/Amp will be draining or siphoning the battery off the Galaxy S3?
 
Apologies if this is a silly question.

According to wikipedia, is impossible to have a micro b to mini b usb cable.

Yes, it’s impossible to use a micro-B to mini-B USB cable to connect a dual-role USB OTG device like the Galaxy S3 to a usual USB DAC.
 
But, a dual-role USB DAC like the VentureCraft Go-Dap X (?) can use the Host Negotiation Protocol (HNP) to switch the USB OTG device from a USB peripheral role (i.e. micro-B plugged OTG device) to a USB host role.
 
"HNP allows the two devices to exchange their host/peripheral roles, provided both are OTG dual-role devices."
http://en.wikipedia.org/wiki/USB_On-The-Go
 
"The Host Negotiation Protocol (HNP) allows the host function to be transferred between two directly connected OTG devices and eliminates the need for a user to switch the cable connections in order to allow a change in control of communications between the devices"

If someone is able to give me a link where i can buy a cable micro b to mini a for the FiiOE07K i can test the Xperia J and some more.
I can't find it and
It's kinda like the 10th time i'm asking

 
 
To connect a Xperia J to a FiiO E07K USB DAC, you can use:
 
. a combination of two cables: a USB OTG adapter cable + a regular USB cable provided by the USB DAC manufacturer:
.. a USB OTG adapter cable: micro-A plug to standard-A receptacle USB cable (micro-A plug to be inserted into a Xperia J)

.. a regular USB cable: standard-A plug to mini-B plug USB cable (mini-B plug to be inserted into a FiiO EO7K)
 
or
 
. a single cable: micro-A plug to mini-B plug USB OTG cable.

The USB OTG cable should be tested with a simple USB peripheral like a USB mouse.

You might be disappointed, the dac on the uha-6s mkii is really holding the amp section back. The dacs not horrible or anything but its more of an after thought than a serious feature.

BTW, sent my Pico back to Justin to get the compatibility issue fixed, will post back here when it returns and I have a chance to test it.

This is the only "non bulky" solution and there are none on ebay.
The only one i found is this:

but i don't know if is otg or not.

DanBa, are there any counter-examples to the DACport's dilemma that they explain here...

Yesterday we spoke about difficulties we’ve faced in getting the HiFi-M8 paired up with  number of phones from Nokia and Samsung.

Recently, we’ve been looking closely at a number of phones from the Android family and have been noticing something rather disconcerting.
 
It would appear that a lot of phones don’t know how to handle a USB audio device (DAC) that announces itself as 192 kHz-capable. That is what HiFi-M8 does, because it supports everything all the way up to 192 on the USB bus.

The dac is using the flagship chip of cirrus logic and nick is working with on the implementation of the chip as his day job. I think how "bad" the dac is, is somewhat overblown. It is going to be better than the dac in most ipods, better then any on board laptop dac and certainly better then the dac in galaxy s3.
I know what you are trying to say though, and might agree that the dac is under performing in comparison with the amp. We'll see

DAC chip != DAC Unit performance
 
 
Implementation is king.

Absolutely agree.. I see the UHA-6S MKII's DAC implementation get badmouthed quite a bit.. and it's almost become an echo chamber argument of sorts between some members.  I find the built-in DAC certainly above average.. and not all that far behind the ODAC, really.  There's more than a few respected, well-informed members I've talked with who would agree.
 
Comparing the ODAC+UHA's amp vs the UHA's DAC+amp, the ODAC/UHA rig is more resolving, dynamic, and tonally precise.. but the UHA DAC+amp is no slouch, in my estimation.  In fact, there's something to be said for the synergy between the UHA's built-in DAC implementation & the amp side's OPA209 chip.  I've found the built-in DAC to deliver some smoothness and provide a little better soundstage width.. things that are quite complimentary to the OPA209 opamps presentation.
 
Exaggerated is precisely what the negative criticism surrounding the UHA's DAC is.  Is it the end all be all, no?  But 'holding back' the amp section & getting treated as an "afterthought" ?  IME: hardly.

"We have a strong suspicion that Android phones don’t know about higher sampling rates and therefore prefer to only work with those devices, which top out at 44.1/48 kHz."
 
 


 









May be, it’s true with the USB Audio implemented by Samsung.




But, it isn’t true with the USB Audio implemented by eXtream Software Development in the USB Audio Recorder PRO app.
My Samsung Galaxy S3, using the USB Audio Recorder PRO app, can transmit a 24/96 PCM stream to my 24/96-capable ODAC

Anyway, kudos to CEntrance for tackling the Android market!
After all, the Android market shows steady growth.

then how u explain that the e07k which is 96 khz capable is working with note 2 "us variant only"  without usb audio recorder. i dunno why its not working with note 2 international T_T , i m really confused why US note 2 capable while international note 2 cant do it.... =.=.

 

[Shultz]

Does anybody know if the odac will work ok without a powered usb hub with a Nexus 7 please?

I can’t explain because the stakeholders, owners and manufacturer of this USB DAC/amp, seem disinterested: no dmesg log output provided …
 
The HeadAmp Pico had an interworking issue with the international Galaxy S3.
HeadAmp Pico owners provided dmesg log outputs.

Folks, Im gonna be totally noobesque here......
 
Im no programmer so I get confused with all the talk of controllers etc etc.
 
I'll keep it simple and hopefully I'll get a " Dummies guide to using *blank* as DAC for android smart phone &/or Tablet "
 
I have the FiiO E17 ( The toughy from what Ive been reading )
And As source I have the Sony S1 tablet & Sony Xperia phone ( Plan to get the S3 )
 
What cables, apps etc will I need IF indeed this is possible???
 
Many thanks
