A/V receiver for Polk RM 6750?

Well I know that others will argue this point but I usually like to over-power a speaker's wattage rating rather than under power it. This is because under-powering often produces clipping which damages speakers. I can't tell you how many tweeters I have replaced because of this. However It's difficult to figure out exactly how much power the Polk 6750's satellite speakers will handle from the specifications. The subwoofer has a built in 50 watt amp so it seems pointless to use a receiver with more power than the subwoofer's amplifier as most of the power is in the bass frequencies. The satellites are tiny, with a 3" "woofer" and a 1/2 inch tweeter. I can't imagine that they will handle much more than 50 watts. So given that, a receiver with around 65 watts should suffice. Marantz, Onkyo, Yamaha, Pioneer and Denon are the preferred brands of receivers for this kind of application.
