Another question for you Denon folk - what's the difference between Denon's AVR#### (4 digit) line and the AVR### (3 digit) line up. I ask because the AVR791 seems nearly identical to the AVR1912 except that the 1912 has streaming and network connectivity and a couple extra HDMI outputs.

But as far as my needs go, the 791 might do the trick at a bit of a bargain in terms of price. Any experience with this unit?
