Good receiver with HDMI and audio processing under US$1000?

For speakers, many audiophiles suggested that you allocate budget at least 2-3x receivers price. So if your receiver is $500, your looking at around MSRP $1500 speaker system (5.1 or 7.1). That's MSRP, so if you can get sale price it would be better.
