I second this proposal.

Current analysis is too limited to draw conclusions about the sound, apart from a low distortion rate from the DAC which is a good point but not the whole picture.

Missing infos:
- Quality, sound and versatility of the headphone amplifier.
- How clean is the DAC output in highest frequencies, including > 20kHz (affect listening fatigue)
- Level of hiss with sensitive headphones (like in-ear)

For comparison, Galaxy S / Nexus S story with Wolfson WM8994 is: great but not perfect DAC, mind-blowing built-in headphone amp.

I'll do 192kHz measurement tonight.
Regarding hiss, It's not easily noticeable, a lot quieter than iPod 5.5G.(on etymotic mc5, 16ohm)
I heard it's output impedance is 31!!!ohm.(NOT CONFIRMED)

Hi, I hope it has good audio quality but as it has USB OTG I would love to use it with my external Fiio E7 DAC/AMP via USB or jack 3,5.

1. Will SGS2 work with Fiio E7 via USB OTG?
2. Does Voodoo have an line-out option via 3,5 jack socket?

There is no such thing as Voodoo for Galaxy S II.

On first Galaxy S, with all Voodoo sound improvements and DAC Direct options, jack output measurements are better (going through the headphone amp circuit) than theoretical specs for the DAC in line-out mode.

I don't think the stock ROM works with portable amps/DACs at the moment. I believe its only limited to flash drives although I could be wrong.

What does all this technical stuff mean in simple term?

Is the sound gonna be improvable? Anything similar to sgs1 sound quality?

It seems SGS2 max sampling rate is lower than for SGS.

I could play music recorded at 24 bit 96 kHz on SGS.
SGS2 seems to be able to handle only up to 24 bit 48 kHz according to Supercurio if the info he found is correct:

Can someone with SGS2 try to play music recorded at 24 bit 96 kHz and see if it works?

SGS1 was resampling (software) everything to 44kHz / 16bit anyway.

Thanks, didn't know that.
I thought the Wolfson DAC in SGS1 could play back at 24 bit 96 kHz when I read specs for it and Voodoo sound used it, maybe it was the wrong spec.

Do you know yet if SGS2 can play back with higher bit rate/sampling frequency
than SGS1 ?
