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,

The classic is a better music replay device, IMHO, because it will hold significantly more music. The touch is more of an all purpose tool. For example, I'm typing this note from an airport on my Touch. And, I use my touch as a controller for my Squeezebox.
any a/b audio quality comparisons playing aiff sources between the two? i believe they use different dacs internally..
Just curious what you ended up getting, I'm debating myself to get an NANO or a Classic.... The new Classic is a 120G which is HUGE compare to the NANO.... I think I just answered my own question, I'll get the CLASSIC!
Haven't gotten anything yet but I'm working on it.

From Red Wine Audio.. "What you may not know is that that the 4th and 5th generation iPods use a very high-quality internal Wolfson Microelectronics DAC (Wolfson DACs are used in quite a few high-end home audio CD players)."

Actually owned one and sold it to a friend, who's currently not using it, so I'm trying to buy it back from him (not using it, but has to find it first..)

Will let you know.
