Geddes' amp on this load?

Amp is Earl Geddes' last known reference, the out of this world great sounding (to me) 2003-2004 Pioneer VSX-D912 receiver: power amp is pure analog chip, P.S. is switching mode (pretty sure), one set of pure analog inputs (6.1 channel). It's sole known Achilles Heel is 8-Ohm rating only, strictly a low-mid current power amp section.

I humbly request opinions concerning the above amp powering the Esoteric MG10 load as shown in the MG10 impedance graph about 10% down HERE

Performance below 150 Hz is virtually irrelevant (used with Duke LeJeune sub design). Someone I know can build an outboard parallel EQ filter to flatten one peak above the bass range.
