The actual official Nexus 7 implementation (with the dock/speakers as host) is the way to go, it will allow charging at least, functioning basically like an iPod dock (presumably even like the new "lightning" port docks which should be digital).

It's possible to charge the Android smartphone / tablet in standard USB audio:

The Google guys should not know the Battery Charging Specification, Revision 1.2.

So far, like the quad-core Exynos powered Galaxy S III, the new quad-core Exynos powered Samsung Galaxy Note II can work with the FiiO E7, the iBasso D12, Leckerton UHA-6S MKII, the ODAC and the VentureCraft Go-Dap X; has some issue with the HeadAmp Pico; and doesnít work with the FiiO E17.

So, in regard to standard USB audio, the behaviour of the Galaxy Note II is likely identical to the behaviour of the Galaxy SIII.

The $43 Samsung Galaxy S3 + Car Stereo Upgrade for WAaaY better sound quality!
http://www.head-fi.org/t/639883/the-43-gal...r-sound-quality

Galaxy S3 > digital USB audio out >> "USB OTG" cable >> Behringer UCA202 USB DAC >> car stereo amp >> car stereo speakers

"...
And so what are the results you ask?

HOLY MOLY!
Not only is the audio quality MUCH improved, but the sound is so CLEAN now. No clicks, burps, or any other weird background noises. Just straight CD quality background silence.
Even my GPS voice sounds prettier. hahah
Bass is tighter and deeper. Highs are more revealing. Everything is so much better that a novice could tell it sounds better.

And yes, GPS navigation works perfectly. If I'm listening to Pandora or an MP3 and my GPS needs to talk, then my music will go several db quieter and GPS will speak up, then afterwards the music will automatically go back to full volume.

Also, one thing I hated about Bluetooth was everytime I turned my car off for just a minute, when I would power it back on the Bluetooth would not consistently reconnect. Well, this USB-OTG has been very consistent for me so far. Music just picks back up where it left off at and is fairly quick to do so.

Cons? Well, I haven't tested hands free calling yet. But I'm told it doesn't work with this USB-OTG to DAC configuration. Maybe there is a bluetooth solution for that. I dunno? And AOSP does not yet support DACs.

Pros? Freakin everything.

Pics are below.


Here is the DAC and the USB-OTG cable:


This is how you configure the DAC.
You can probably also use the headphones output instead of the stereo RCA, but I didn't try it.


I wired up my USB-OTG cable to my iBOLT dock. It comes up through my dash defrost vents.


This is what the three connectors on the USB-OTG cable look like:


Here is the DAC being wired up. I taped up the non-used RCA's to prevent anything bugging with them.


I wrapped up the DAC with DUCT tape.
Not sure how or why the pic is sideways. It looks normal on my desktop.


Hid it behind my dash.


Here is the USB-OTG cable with my iBOLT dock.


The car stereo w/audio cable attached. Some car stereos have the 3.5mm connector in the back. Or a dual-RCA input. I'd prefer one of those to have a cleaner install. Maybe someday I'll upgrade my car stereo.


And here is the finished product. My S3 docked, charging and outputing beautiful digital music!

Are you aware that you are at Hydrogenaudio? You know... where there's a Term of service number 8 that goes against gratuitously giving audio quality impressions.


But even then, haven't you forgot to say versus what are you comparing it to?

I was actually interested in the topic name but should be renamed the DanBa/BaDan show... blink.gif

That all aside - one gentleman asked a few pages ago, 'what's wrong with the internal DAC'. I like the ABX philosophy here, but I don't know how you can do a ABX with the internal dac vs external. I know over on soundexpert they tested devices but it's an aged list.

Using the same philosophy, and coming to the realization that I thought I had pretty good ears.... but find that 96k aac files are 'pretty good' for listening on a portable level AND being a recovering audioholic - I wonder how much 'better' adding complexity is to this system.

Record the two outputs with a good recording device, and ABX that, I guess?

If you read the linked post, the guy has compared his car stereo system with analog USB audio out (i.e. Samsung-proprietary line out) and with digital USB audio out.

Analog USB audio??? What does that mean?
[Edit: Ok, i found this link that somehow talks about using the USB cable as an analog output... Never heard of this before, so i cannot even talk about how it is supposed to be implemented)

So.. I have to assume, somehow, that the analog circuitry of the SGS3 (used for headphones) has operational noises, similar to those that happens on computers when moving the mouse or reading the hard drive?

At last, it is not possible to get CD quality background silence, because he's using the (analog) line in of the radio.

Not sure what would constitute a 'good recording device', but what I have available is my laptop mic input where I could record some sample via the phone jack to HD and then compare that to another sample the same way. Is there a 'standard / acceptable method' to match the output levels so there's no loudness bias? Sorry, this is probably OT for the thread a little.. Wait... I don't even own a DAC.. crap... maybe we can use a sample off of the sample section here and we can swamp converted samples for ABX'ing?

Wow, that looks messy. Especially for the car, I've realized that bluetooth is probably a great thing. I've been temporarily using my Nexus 4 with my little Jambox stuck on my dashboard, while I figured out what to do with the gaping hole where the (now stolen) stereo used to be, without having to get another one. Music and receiving calls is pretty seamless. So I just bought this little BT adapter, which comes with music controls as well. Will be connected to a little amp and most of the stuff will be hidden inside the hole or somewhere else. When something reasonable comes out, I'll get a Qi wireless charging dock for the N4 and I'll be completely wireless in the car.
