I'm not sure if this is the right place for this topic, but I am wondering about the onboard DAC on various iPods. I have a 4th generation Touch, a Classic (aluminum 80gb), and a 2nd generation Nano. How do the onboard DACs compare on these? I know its subjective blah blah blah but general opinion and niceness: which one is best?
 
Edit: I'm fairly certain the Touch and Classic have a Cirrus, and the Nano has a Wolfson.
