Elvis,
I would highly recommend an AVR 354 or its older equivalent the 347 in the H/K family. Fist off even if you don't think that today you need HDMI, eventually....you certainly will. The newer 354 can decode HD sourced audio formats, has superior video processing power and more advanced in room set-up.
Granted that 7300 is a powerhouse with 75 amp HCC available. That's real world speak for
Grande_Cajones .
Spec links for them all here:

347

3808
You can probably grab a 347 (last years model) for ~1/2 of the 7300's $. It or the 354 would surely power those speakers. They are quite easy to drive., you know. If you were looking at harder to drive speakers then the 7300 might be a better choice; audio wise.
Good luck and let us know how the decision goes.
