^ well that doesn't sound right at all.
Most likely you got an email response from a complete
moron. Hopefully all of them aren't that stupid.
Not sure why the audio output is so bad. I've tried searching
the googles for info about the dac and opamp but haven't
found any real info.
Some generations of the iphone used better dacs and amps
than others, but overally I thought the 3g I had sounded pretty
decent.
Sad to suggest this, but a mini headphone amp might be your
best bet when doing any major listening.
Cheap ones can be had. The Fiio E5 gets decent reviews from
all but the audiophiles. I haven't tried it out yet, but I will be getting
one from amazon soon. They sell for less than 20 and they're very
small.
