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,

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.
I have the Ipod, I don't know the technical generation of it, I bought it new 9 months ago and it has a 120 or 160 GB capacity. My son has the touch 16 GB (because he likes the games/downloads/etc. . .). Listening directly to the two pieces, I hear no difference.

To me, and as referenced about the D Kraul 60 mb/song (by the way, that is a great album) the non-touch version makes more sense. I think the touches are up to 32 gig now, still a fraction of what the "5th generation" is capable of holding. For that reason (and the fact I hear no difference based on high res. music), I would get the biggest capacity. I don't like to constantly be adding and removing music. I like different music based on my mood and don't want to be limited to 20 albums when I am traveling for a whole week.
