Welcome to the forum sgtpepper.

The Pioneer Elite seems like a very capable AVR. Just make sure not to run the AVR beyond its limits and you should be fine. Your room is not that big (listening distance) so I don't think there will be a problem. Any problems like the AVR shutting down would likely happen at very loud playback levels.

Enjoy your new speakers!
