Does this mean I use the tuner portion of the NAK only then plug everything else into the NAD
As Modi said, yes, BUT only if you
A. Need a tuner and
B. If the pre/amp section of the NAD sounds better than the NAK. I'd try them both w the same source and see which one you like better. If it's the NAD then you can do as MOFI said to get FM. If you like the NAK better, then there's no need.
