Among many hidden and official features of the new OS, there is speculation, hype and perhaps even a bit of placebo stirring among the enthusiastic audiophile crowd; apparently, the new OS has improved the sound of both the iPhone and the iPod Touch. I am a keen member of headfi, a great headphone-devoted forum where you can geek out with enthusiasts, trade, sell, barter, discuss and make noise about your favourite phones, amps and cables. Since 2004, I have been perusing heafi and since 2006, verbosely posting. In my short time, I have seen the coming and going of many hype threads and and others that are true treasues. As a portable audiophile, I am more than interested in claims that OS 3.0 improves iDevice sound quality.
