So they announced Jelly Bean for the S3...Any thoughts on whether this'll fix FiiO E17 compatibility?

I don't think it will, the USB audio support in Jelly Bean seems to be non-standard. My E7 and E17 both fail to work with my Nexus 7 on Jelly Bean.

i like the blue......

Hopefully that doesn't mean DAC's that currently work on the S3 with ICS stop working when it receives the JB update.

I'm curious as to what the best non-E17 portable is and whether any of them outclass the somewhat lower end Wolfson...

"I just tried connecting the Pico to the S3 again.  It works!  I have no idea why it didn't before.  There were times when I’d connect the D12 without success too.  It seems you have to connect everything together in the right order.  First connect the cable to the S3.  Then connect the DAC to other end of the cable.

 
Regarding the engineering at Head Amp: It’s the real deal.  Their products are expensive, but their results are second to none.  I’ve had a Pico for more than 4 years now, and I’ve yet to hear a better 16 bit DAC.  As of now, I’d rate it as the top option for the S3, as it’s smaller and a little better shielded than the D12.  There are a LOT of DAC/amp combos out there now though, and few people have heard enough of them to make a proper comparison.
 
For those annoyed with the external DAC discussion, let me assure you that the S3, decent DAC chip or not, is not currently a suitable source.  The noise floor with my JH13s is nothing short of abysmal.  It probably sounds Ok with an efficient pair of full size headphones.  I’ll try it out with my LCD2s tonight.
 
I understand the desire to separate these topics.  Comparing phone headphone jacks is like comparing Honda Fits and VW Golfs.  DAC/amp combos are more like Lamborghinis & Ferraris."

Right but I heard that because of optimization of the HPO, outside of the noise floor, the HPO sounds better...? Is that true?

We could compare only entire audio systems:

 

Same S3 player > digital audio stream > internal DAC > internal amp > headphone out >> same headphones

 

Same S3 player > digital audio stream > USB out >> external USB DAC >> external amp >> same headphones

 

The internal DAC of the S3 is not only the Wolfson WM1811 chip. It includes other stuff like clock or power supply module.

 

We should only compare DAC chips like the Wolfson WM1811 of the S3 or the Wolfson WM8740 of the low-end USB DAC/amp FiiO E7.

"But the chip is only half the answer — correct implementation is the other half. Not everyone is an experienced circuit designer. If someone tries to use a great chip and gets frustrated, they post on the Internet that the chip is bad and other people read that as true. We prefer to have our customers listen to our products and make their decision on the sound quality, not on what they read about chips on the Internet."

Another example: a Rosita Pi at 10 650 € is basically an Apple AirPort Express at 89 €, with a same DAC chip, but with a much more precise clock, a much more linear power supply module or a big RF-blocking enclosure.

Has nobody done this comparison?,Are we sure that with the usb and external amp will have better sound? And if yes .... How mutch better?

This question becouse I think the usb output of a galaxy s3 or other phone is not a top quality option, I think we wil get better result using a line out (iphone or sony z walkman for ex) + amp when it is possible

But I really don't have experience I am gratefull to anyone post an opinion based on experience (I'm interested particularly on experience on s3 +dac + amp+ headphone  VS s3 + headphone ).

Thanks

Yep! In experiments, you change only one variable at a time. Middle school science has its uses wink.gif

 

So the question is up to what point will an external DAC/AMP help. I'm sure some >$1k DAC with a >$1k amp will trounce the S3 in terms of sonic quality, but will the same happen with say a HM-101 paired with a cMoy? Or a more relevant, will buying an E7 result in a discernable difference?

 

I suppose there is still no way to bypass just the amp in the S3 just yet.

At least, the quality of the USB out of a given Galaxy S III depends on the type of USB DAC, asynchronous or adaptive.

 

Asynchronous USB transfer uses a high-precision clock of an asynchronous USB DAC like the HRT Music Streamer II that interworks with the Galaxy S III.

 

The quality of the USB out depends also on the implementation of a given adaptive USB DAC: it could have a high-precision clock that is only loosely coupled with the clocking of the Galaxy S III.

Samsung Galaxy S III USB out bypassing the internal DAC:
Samsung Galaxy S III > digital audio stream > micro USB connector >> USB OTG cable >> standard USB DAC >> amp >> headphones
 
Samsung Galaxy S III headphone out:
S III player > digital audio stream > S III internal DAC > analog audio stream > S III internal amp > 3.5mm 4-pole connector >> headphones
 
Samsung Galaxy S III line out bypassing the internal amp:
S III player > digital audio stream > S III internal DAC > analog audio stream > micro USB connector >> Samsung audio dock >> amp >> headphones
