Not completely like the iPod LOD, the way you note you still have access to the internal amp as you can still use the volume on your S3 and as a result of double amping.

This kind of volume control (i.e. digital volume control) is working on the digital output signal path.

 

 

 

 

"Digital volume control is multiplying the numerical value of the sample by a factor.

This factor is in general < 1 but not all of the time...

By design the audio is no longer bit perfect when digital volume control is applied...."

Correct me if I am wrong but I believe if you leave the digital volume on 100% this is not the case.

It is a digital volume control and is not sent through the phones amp.

Yes, if the digital volume is on 100%, the digital volume control is not applied.

Even if it is applied, the audio data is bit perfect because n * 1 = n.

I was in a similar position once, when I was looking for the best SQ out of my Galaxy S3.

I would like to share my journey with other members, who are looking to try an external dac and amp via usb out from their GS3.

 

I started off with Fiio E7, which didn't work with my S3.

Then bought the Stoner Acoustics UD100, which actually worked. It was the first time I tasted audiophile grade music...!! 
Got my friend's Fiio E11 to try with the UD100, which further improved the SQ.

 

After some searching on internet, I literally gambled on a Linearossa W3 dac/amp combo from Jaben. It looked portable, but had amazing specs up its sleeve, so thought it could serve as a desktop device. 

Finally, when I received the unit, I didn't expect it to work via usb out. But, to my surprise, it worked flawlessly.

The sound became much more cleaner than with the UD100. It was a different experience altogether. Coupled with a powerful amp, the Linearossa W3 was able to drive the Denon AH-D5000 and Senn HD650 beautifully !!

I finally got myself a perfect portable rig with my Galaxy S3 at its core. With a large beautiful screen, its unrivalled android UI, expandable storage, plethora of choices for a music player app, the Galaxy S3 is a no-nonsense DAP, period.

 

To all those people still thinking about going for an external dac/amp with the Galaxy S3, I say you are wasting your time thinking....Go and get yourself a good dac/amp combo and you will never regret.

Moreover, if you ever end up selling the GS3, you'll still have the device for desktop use or for use with a DAP...

 

PS: I am running my Galaxy S3 GTI9300 on Paranoid ROM
