You are comparing 2 completely different sounds. Mac = rich, rounded, a little burnished, more of a traditional tube sound than ARC. ARC more transparent esp in the upper midrange/lower treble where the MAC can be less revealing. ARC is better at revealing textures and color and provides a much broader soundstage.
That said, I've heard the 2301s in an all MAC system (C1000) with your speakers and IMHO this is one of the best synergies between electronics and speakers for MAC.
But overall I prefer the Ref 250s, esp with a full ARC system. Only problem is I've never heard your speakers in an all ARC system.
