I'm not sure either option would be best for Focal. The Anthem is very clean and high resolution, but this type of match with Focal is generally not a good thing. The focal can be very bright/harsh with equipment that is too "solid state" sounding. On the other hand, the Marantz would be a better match but it could turn out being too slow/warm with rolled off highs.
I would actually pull that McIntosh MX-136 and Krell amp out and hook them up to the Focal. That might be the best solution, unless you wanted to spend some good money. For an alternative "new" receiver, maybe Pioneer Elite VSX-503 or even an Arcam HT receiver if you can find one in your budget.
