Matt, here is another one for your consideration. I have the Pioneer A9 which I am very impressed with. The A9 is essentially two mono amps with twin toroids and hefty capacitance in one chassis. It is conservatively rated and has no trouble with any of my Axioms including the active LFR woofers. It is dead quiet! I get a wide, deep soundstage with very well-defined images.

The one below may be similarly good to mine but with less power.
