littleb,

That was my own impressions, too, when I listened to the Axioms (M22's) for the first time at Mike's (mwc) house. I was impressed by how small they physically were, and then by how big they sounded. I didn't feel a brightness / harshness / aggressiveness at all, either -- it sounded very neutral to me. No wonder the Axioms timbre-match very well with my Hales.
