I've beaten SoA a number of times using the following strategy.
First, I always have at least 1.5 mages (usually Nalia and Imoen).
PRE-BATTLE:
Cast Simularcrum (or Project Image, I suppose) on both mages. 4 mages.... more magical firepower.
Summon the toughest monsters possible.
Cast all of your best buffing magics. Drink all the best potions.
Place you summoned monsters near where Iren's demons will appear.
Place your simulacrums at a decent distance from the where the demons will appear to keep them out of melee.
Start the battle.
Have your monsters attack the demons. Have your best tank attack Irenicus. Have your other tanks attack the demons. You want to kill the demons ASAP. At some point a few rounds into the battle, Irenicus will cast a death spell that will dispell your summoned monsters, so use them quick and kill Irenicus' monsters. The Horrid Wilting spell is a great support spell for this purpose.
Have your mages and their clones take down any defenses that Irenicus might bring up. Otherwise, have the mages cast spells to suppose your tanks attacks on the demons.
All things considered, killing the demons is your first job. It's easy to kill them quick if you focus on them. But keep Irenicus occupied. After the demons are toast, then throw the kitchen sink at Irenicus.
