It depends on the sound qualities you are going for. From my experience and taste, Audio Research and Sonus Faber are a much better match. Macintosh is very mid range and bass heavy, notably lacking detail and treble. Audio Research is highly detailed with great midrange bloom , musical with natural rhythm and pace, so these are the great combination.
While I slowly migrated towards this combination over my fifty years of pursuing the high end, only after assembling these together did I hear this is one of the great synergistic combinations: Audio Research, Sonus Faber, and Transparent cabling. I have heard the combination of Mac + SF many times, but it is not at all appealing to me. It may appeal to folks that love rock… although that combo is bested by Mac and B&W.
