No. Why do people listen to those who did not test things thoroughly...meh, whatever.
I'm telling you, the DAC inside the phone is excellent, and sounds excellent. Believe it, or don't believe it, your choice.
Here are some measurements for you:
And note that is measured without an external amp on the galaxy S, while the nfb-12 has a powerful amp inside it. If Galaxy S had a better headphone amp inside it, the measurements would be even better.
The only reason NZtechfreak heard an improvement in sound when he plugged in the E7 is because of the amp. I challenge him to plug in a pure amp, without a DAC inside, and he will hear the same improvement.
That's the same reason why I hear a MONUMENTAL, night and day difference between using the headphone out of the phone, and using a good quality amp between the phone and headphones. It literally goes from sounding like muddy quiet mess, to sounding unbelievably good by any standard. As I said already, impossible to tell which is which in a blind test between Galaxy S and a 800$ DAC.
And there is no crackling when using the Galaxy S as source, I never heard any crackling, or distortions, or anything of that sort.
Just to make sure there is no confusion - the Galaxy S may not have crackles / pops, but the S3 does - Categorically, without a shadow of a doubt...
...We are all talking about the same device?!
Anyway, I'm more than happy running the Fiio E7 / E11 combo, if I am missing out on something by having an extra box in my chain, so be it - I know what sounds good to me, whether it is backed up objectionally, or with graphs etc...
Oh, and the little tiny Monster Trumpets definitely are not full sized, and the poor little phone cannot even drive them with authority...
