I’m running a pair of XA 60.8s to the Magnepan 30.7
Just back from hols, keep the 12ft cables you have, as those XA60.8’s "could" be replaced in the future, as their lowish power in a big room to take those speakers may become a problem after a while for you, with those big mulit paneled Maggie 30.7’s.

And then you may then get a bigger poweramp, maybe stereo again, and you need the 12ft cables back.
