Welcome to the forum!
I think that the first question to answer is - do you like the speakers? Have you heard them? I think that people should audition several speakers before deciding on which ones to purchase. That doesn't mean that you need to spend weeks and audition hundreds of speakers. I do think that it's a good idea to listen to more than one pair of speakers, though, because it let's you know if there are others out there that you like better (or like the same but that cost less).
From what I've read online, that receiver (at least the U.S. model) can handle the impedance of those speakers without a problem (the receiver will handle a 4-Ohm load, and the speakers are nominally 6 Ohms). Those speakers have an efficiency of 89dB, so depending on how loud you like to play them, you might find that the RX-497 doesn't quite have enough power to play loudly and clearly. It might play plenty loud for you, but I wanted to mention it as something to consider. I highly recommend that you try out the combination at the dealer before buying them, or get an agreement with the dealer than you can bring them back if you don't like them.
