iPhone 3GS sound quality

[JCW]

I'm no audiophile, but what has put me off in the past is the 'blandness' of MP3 players and now having finally taken the plunge and bought an iPhone I've noticed that things haven't improved.

Playing the same track on iTunes compared to Windows Media Player on my laptop brings a noticeable difference, with the iTunes version lacking warmth and sounding like its missing layers of the music. Is there anything that I can do to improve the sound as the portability is useful, but plugging it into the car sound system is like listening to a cheap tranny?

Thanks.

Some interesting stuff, so thanks. I've deleted all the tracks and re-ripped them on to iTunes so I'll repeat the process on the iPhone and see what happens.
