The A630 is 120Hz, and the A650 is also 120Hz.
The A630 has a 40,000:1 contrast ratio, and the A650 has a 50:000:1 contrast ratio, which can be noticible, but not like "night and day" noticable to some people. That's one that you'll have to look and see if you can decipher the difference in picture quality. That's really the ultimate test.
The A630 has 3 HDMI ports, the A650 has 4 HDMI ports.
I don't want to risk suggesting one over the other, so I'll leave that in your capable hands.
The 9-Series is currently out and on display. What makes it different is instead of having CCFL's (Cold Cathode Flourescent Lamps) behind the LCD screen, we have LED backlighting. Each of the LEDs operate independently and can dim or go off, depending on the picture being shown, which makes a huge imporovement in dark scenes and color capabilities. I'm not sure, but I believe there are no less than 54 individiual lights behind the screen, and that local dimming produces more greys, colors and darker shades of black. The contrast ratio on that is 1,000,000:1, and although I'm not sure how that translates in comparison to the other units, that is our flagship, top of the line model of LCD this year.
So I hope that additional information helps.
Keep me posted!
