Geez, grifter, that was a very scary beginning to your post. I'm betting a lot of other Axiomites will have an emotional response until they realize your intent. Whew!
Don't worry about your receiver - it will be great. Somebody more savvy with that model will surely chime in, but I can say with some certainty that it is not going to have any trouble driving your setup to very satisfactory levels. I don't think the QS8's represent any load problem at all; I have them attached to a Denon 1804 (which is less robust than your Yammy) and everything set to 8 ohms. No problems.
Enjoy your new speakers, and next time, don't try to scare us!
