Should be OK, just don't go crazy with the SPLs. Keep in mind those are 4 ohm speakers and may delve lower than that a lot of the time. Just be mindful of your level of output.
Have you purchased this AVR or speakers already?
The TX-SR805 would be much better fit to drive those speakers, and can be found for very reasonable prices. Probably the best bargain in AVRs out there right now.
