Best audio quality - Apple iTouch vs iPod Classic


Hello all,
Any first hand thoughts / comments on which current Apple iPOD family product has the better DAC / overall music quality? (iPod classic / iTouch / iPhone)

I do not have an external DAC so the Wadia 170 iTransport is not an option at this point.

I've ripped a couple of red book CDs to AIFF and copied them to my iPhone, and I'm impressed with the audio quality when compared to my Oppo. BTW Each song on Diana Krall's "Live in Paris" is about 60 megabytes.

Although using an iPOD family device will not replace my CDP or TT, will be yet another source, when convenience is priority.

Regards,

thanks for starting and sustaining this very interesting discussion.

Can someone please tell me how to identify a fifth generation or sixth generation iPod?

And what are the battery issues with these models, e.g. can they be replaced, etc.?

Thanks in advance

:) listening,

Ed,
Here's a URL from Apple on identifying IPODs http://support.apple.com/kb/HT1353

Batteries can never be user replaced on any IPOD.

Could not get my hands on the 5th gen 30gb IPOD after all.

Also after thinking it through, since FLAC takes up so much space, I think I'm going with a squeezebox solution instead.

Cheers,
I have the Bose noise canceling headphones. I prefer the sound of my 5th Gen iPod over the iTouch. I gave the iTouch to my kids.
