It's been discussed before and I have tried all the eq, sound enhancer and pre amp adjustments suggested but I'm still getting unacceptable distortion and crackling on my iPod. I have my songs at 320 bitrate, I'm using a new 40GB iPod with iTunes4 and have recently ran Software Update. Anyone else having similar problems? is there a 'fix' I've missed?

To quote Apple's knowledge base "iPod is designed to provide the best-quality sound. iPod has a powerful 60 mW amplifier so it can deliver audio as loud as you want. It also has a 20 Hz to 20 kHz frequency response, which means you can hear distortion-free music at the lowest or highest pitches. Even the iPod headphones are designed to give you the best-quality sound."

I'm no audiophile but I can't help but disagree with Apple and ask what are we paying for?
