What does everyone power these with? I was planning on using an Onkyo 3009, because I like Audyssey calibration and Audyssey DSX for movie watching. However, the guy I talked to at vanns strongly suggested against the Onkyo. He said since the Onkyo runs hot, I can agree there as my 707 definitely runs hot, that running 6 ohm speakers with it would be a very bad idea as it would just run even hotter. He suggested using a Yamaha, saying that Mirage and Yamaha pair very nicely together. Only problem I have with that is that Yamaha doesn't have Audyssey, and I can't find any information about how their 9.2 channel creates the extra channels. So, what do you guys use?
