Is the E07K MFI rated for the older Ipods? I have an Ipod Nano 5g and I'm trying to find something that can work as a dac for it, not just an amp. Thanks.

Not sure, I haven't tested it with the older 30pin configuration. You would need to get a camera connectivity kit and try it out. I think Fiio also sell a 30pin to mini usb, specifically for this use.. I don't know that it will work with the E07K though. Cheers.
