The most important aspect of an A/VReceiver is having enough of the proper connections. If you have 5 components but your AVR only has 3 inputs then it doesn't really matter how good it sounds to someone else.
So first tabulate how many component video, S-Video, fiberoptic audio, HDMI, etc etc etc you have now (plus what you might need by Xmas), then you can start narrowing-down your choices.
