What's a good mid-range Home Theater Receiver ? - mid range receiver 2010

I'm not an audiophile, but do not enjoy music and video in a quality home theater. I have a 52 in plasma, 1080i, DVD, HD DirecTV TiVo W and some gaming systems. This is a solid that an HD receiver / V supplement and quality music?

I want to stay under $ 500.

I saw some recommendations for the Panasonic SA-XR57 and SA-XR55S, but I have no experience w / Panasonic products.
