What a/v rec. would best power 6 in- wall/ceiling speakers in kitchen,dining,and living room- (appx 500sq ft)?

2 speakers in living upper wall, 2 in dining upper wall, 2 in kitchen ceiling. They are all practically in the same room, with two being separated only by kitchen wall. Thanks!

Pretty much any 7.1 receiver will work fine:
