A DAC can only accept a digital audio stream (typically via toslink/coax) where the player (e.g. iPod) is decoding the audio files from, for example, AAC to a digital audio stream.
In the case of an AVR that uses data, it is reading the audio files off the device, and decoding the audio internally.
The iPod classic does not support digital audio out of its dock connector, so you cannot connect it up to an external DAC.
However, if a device can read the data off the iPod, then it will be able to play the files digitally, as it is reading the files, decoding them to digital audio internally, and then running them through its DAC.

I want to hear all the details which im sure are all gone due to the compression process, again thank you very much
The analog line-out of the iPod Classic looks pretty good, but if you buy an AVR that supports digital playback via USB, such as the Denon mentioned here, you should theoretically get better sound from it.
But there is absolutely no point in doing this if you are storing compressed files on your iPod that are below 320k MP3/256k AAC, and ideally you would be using Apple Lossless.
