To me they are both great recievers and you can't go wrong with either one. From what I've read here both will sound great with axioms.

I got the denon 2805 and will continue to get denon recievers..Why? It's sorta silly but denon gives you all the information they have freely. If I want to control my denon through the serial port I can. If I need help on how to do something the info is there and easy to get versus pioneer which makes you sign up for any info.
I know it's silly but it makes sense to me.
