Mark,
I use two M800a on the Sarastro2 and currently experimenting with vertical biamp vs bridged. Even with 93db, the increased power in bridged config offer more grip to the bass. Biamp adds delicacy and significant increase in frontal to back imaging. You will not go wrong in either of the choices, plus and minuses either way.
Biwire also increase transparency.
Best of luck with you purchase.
