I understand, I really was not responding to your post, I was just next inline.
I know historically Onkyo has been one of the brands not favored by Axiom. Years ago they did a lot of lab testing with the 80's and that was one brand that did not rate well.
The 80's are a very easy to drive system, that does not dip below 4ohms across the frequency range. To me it is amazing that any solid state AVR would have issues. I'm not really up on Onkyo's latest models, but have heard they have a better track record 80's and other 4ohm designs.
I've used my Denon 2805 to drive my 80's to levels most people would fine satisfying. In reality, your only using a few watts with dynamic peaks from time to time. Any 100 watt AVR will accomplish this task.
But like you I love my Odyssey Khartago Mono's. The 80's never sounded so good...
