Here's my review of the Pioneer Elite SC-67 I did today on Amazon.com. I'm including it here because of my mention of Axion Audio in it.
The best receiver I've owned, so far., May 5, 2013

I love Pioneer receivers. I had a low end Pioneer Elite before that developed a problem that was going to cost too much to fix, so I replaced it with a medium priced Denon. I always heard good things about Denon so gave it a try. I couldn't get it to sound right in my living room setup. Lows were weak, and highs were grating on the ears. After much adjusting and advice, I gave up, and ordered this upper range priced Pioneer and I'm glad I did. The only con is it's inability to equalize the lower bass, like the Denon's can. But I prefer too much bass as opposed to not enough. I can always turn the gain down on the subwoofer. I also like that it has multiple saves for MCACC, so I can drag a loveseat up close and just switch to a different preset sound calibration.
I've had this unit for 5 months now and I'm still loving it more every day. I'm running a 6.1 system in my living room, using Axiom Audio speakers, and a calibrated 65 inch Panasonic Plasma VT50. I'm in A/V heaven. Using an Oppo blu-ray player, without any video enhancements from the receiver.
