Set your input level controls on the amp to max and your impedance switch to 4 ohms. If these are the older (original Henry Kloss) Advents, they dip a little below four ohms. The NAD should be fine with this.
I ran one set at 8 ohms into a 4 ohm impedance some years back and had no trouble. It sounded better that way (more powerful)
Also, I believe this amp has a soft clipping control. If it does, turn it off. You don't need it.
