If I remember right, the Onkyo 806s are in use by a few forum members and worked fine. Onkyo is just not as consistent in their ability to drive the M80s, so Axiom doesn't give them the universal stamp of approval. Hopefully someone who has tested the 806 first hand will chime in before long. You might also try a search for that model number to see what comes up in recent posts.
