Not in depth. I have used a Yamaha before (661), and while I found it to be an OK receiver, I did not like Yamaha's room EQ and find Audysey to be vastly superior. For that reason I decided to not buy another one.

The only other receiver I gave serious thought towards buying was the Onkyo 905 or its sibling, the Integra 8.8. I decided against it because of too many user complaints and the fact that it runs hot to the touch. Plus its VP is altering the color space from 4.2.2 to 4.4.4. I find it troubling for any electronic gear to run hot to the touch because heat kills electronic components. If I really needed a good on board Video Chip, the Onkyo would have been harder to pass up, even with its quirks.
