Hi Todd,
I think that those two alternatives might very conceivably be sonically indistinguishable, but if there is a difference I suspect that the better alternative would be to use regular cables from both A and B.
That would keep the mid/hi frequency currents and the low frequency currents separate nearly all the way back to the output circuitry of the power amplifier section of your NAD. If you were to connect biwire cables to A, those currents would flow in common through the switch that selects between A and B and A+B, as well as through the wiring between that switch and the output terminals.
And of course connecting separately to A and B has the added advantage of enabling you to use regular cables.
Regards,
