manicm: ......because Apple often change the internal DACs, and not always for the better as some believe with the current Classic.
Manicm, from a link to cnet uk you posted under the ipod sounds better post, it is comparing the difference a new DAC has made;
This difference should have no practical impact on your decision to buy a new or old iPod. If you've read the sound quality difference is dramatic, don't worry -- it isn't. The differences are only very subtle through bleeding-edge gear, so should only influence you if choosing an iPod for bleeding-edge listening conditions or if used with more costly hi-fi equipment.
Ultimately, the best advice is to trust your ears. If you can't tell the difference, and enjoy the sound, that's really all that matters. But please do yourself, your iPod and your music one favour: don't use the earbuds that come with the iPod. Just using a half-decent pair will make more of a positive difference than anything we've explored today. -Nate Lanxon
However, I do worry that now the ipod is well and truely established in the market, Apple do not need to make the same effort regarding getting the sound quality the absolute best that they can, as they did at the start.
