I have a Denon 3808CI. It sounds really good or so I thought. I replaced an Yamaha RX-V1000 with the Denon. I recently purchased a B-Stock Emotiva XPA-5. I am using the Denon as my Pre/Pro until Emotiva comes out with there new XMC-1. I can tell a big difference with the XPA-5 driving my Paradigm Studio 60's. They are 8ohm nominal. So I would think that an XPA-5 would do a much better job of driving your Axiom's. Also there customer service is awesome. Not sure that Denon's customer service is even in the same class.

Check out some of the Emotiva threads on other forums. Also their reviews on ther equipment all seem to be good. I find it hard to believe that you can do better for the money.

Hope this helps.
