I have a very basic question..
 
As I discovered that Lollipop supports native usb audio out. My question is will the low-end cheap devices (with no usb otg support by manufacturer in spec sheet) support this feature after getting updated to Lollipop?

Short answer should be No. It's like e.g. with Samsung S4 Mini, no USB host mode, doesn't matter which ROM you are using.
 
Btw. it is a quite difference to support external USB drives or USB devices like USB DACs. I know devices they support USB drives, but no other USB devices.
 
The cheapest Android phone without contract I know with full USB host mode and Android 5 as ROM is the Motorola Moto G / Moto G 2nd.

  Thanks DanBa for all this info! It was nice of you to consolidate it for everyone. Hopefully someone will find a solution to make this work. Someone on diymobileaudio.com is running an ipad in his car through a DAC and then to his stereo. I don't even own any apple products, but if running an ipod could get the full 320kbps I might do it, I know my head unit is supposed to support that. I can still return the headunit I bought and get a new one if that and or getting a new phone would make this work. Im not sure if "full mirroring" means they are getting the full 320 kbps stream?

 
You can do that with a USB DAC compatible with the Galaxy S3.

I think so.

In terms of SQ there is no difference. Take what for you suit at the best

  I would go for the device with most storage space in this case.

i don't think its correct though, as using different transports make a difference, i don't if all others on this thread agree with u and an explanation to ur response is appreciated

You're just pulling digital signal into the external DAC. The DAC is then responsible for quality. That's why it doesn't matter where the digital signal comes from.

Well if it was only as simple as some who have posted suggest.  It is not!  First, it is not as easy as sending bit to a dac and all the "quality" happens there. 
 
Did you know, for example, that the Android framework will take whatever sample rate files you feed it, let's say redbook and upsample to 48khz?  And did you know it will downsample a 96khz file to 48khz.  That is for all the players I know of for Android except one, UAPP.  And that is before it even gets to the dac......................
 
And when you move over to the IOS platform you face a slightly different scenario.  The stock Apple player will not play back anything above 48khz (at least ios 7 on my ipod 5).  Other players will.
 
So you need to ask yourself, what type files will I be playing back and then decide on some software candidates for each platform.  They do sound a bit different even when playing a 44khz file with good headphones.  Not that the differences are big, but they are audible to an educated listener.
 
My experience has led me from the ipod 5 to an Android platform for casual outdoor listening.  But it is still nowhere near as good as a properly vetted computer based setup used in the house.  YMMV :)

Not if you use USB Audio Player PRO.

Or use the free HibyMusic app for Android devices, it provides like UAPP the driver support aswell.
 
 
@hykhleif
 
It makes of terms of SQ no difference which one you use, I'm talking about e.g. regular 16/44 FLAC rips, higher bit rate = larger files, less space on your small storage (mostly only up to 128 GB micro SD). All this stuff about down-sampling/driver support you need to know (as bixby said) yes. Still the basic question about the choice depends on other aspects and not on terms of SQ, like (@DJScope) said it's a digital signal and the micro iDSD do the "sound" part, your devices providing only the files for playback.
 
I use a Samsung S4 with 256 GB card mod with UAPP with the micro iDSD and I'm very happy with this setup: http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/5865#post_11120441

Is the iPod even capable of streaming 24/192 files?
