The McCormack DNA-2 is rated at 300,600,1200 @ 8,4,2 ohms. I think the nominal impedance of the MG3.6r is just under 4 ohms. I really liked the stock DNA-2 Deluxe with the maggies for a couple of years and replaced it with a DNA-2 Gold SMc Audio revision amp. Highly recommeded. If you got the stock amp you could upgrade it at some point or find a used Rev A or better. Let me know if you need more info.
