Springbok, the MA-2 amps are quite comfortable driving a 4 ohm load. You likely don't need the autoformer for this combination unless the speakers have some crazy low minimum impedance dip. The MA-2s work beautifully here with Eidolons, a nominal 4 ohm speaker with a 3.6 ohm minimum impendance.
Keep in mind that the autoformers have their own sonic signature that will be added, and they will introduce some veiling to the sound.
You might be well served to get your speakers and listen to them with the MA-2s first before diving into the autoformer.
