I'm a huge audio guy. In fact it's the industry I am in.
It used to upset me that such high end phones like the iPhone had such terrible quality. Then I came to a few realizations. Not enough of the market is "into" audio for Apple to spend resources on that feature set. If you're not going to gain additional sales or users from a feature, why spend money on it? Doesn't make any business sense. Also, most people that are "into" audio will have a legitimate home and/or car setup where they listen to their music. The phone is not the medium for the audio listening.
