Go with the 1800, you wouldn't notice the difference of only 10 watts. Also, the 1800 has more HDMI inputs and 1.3A. I'm using an older 2600 with Paradigm Reference 40's, 20's and Center and it has plenty of power for those. It's also 130 watts. Usually using a Parasound HT2250AT amp for power but its in the shop right now and I hardly notice a difference between it and the amps in the 2600. The only problem that has been brought up with the 1800 and 2800 is its clipping of whites and below blacks with its video processing. Read all about it on the 1800 & 2800 threads. Also, may want to consider the Onkyo 875 or 805. Those can be had at great prices right now also.
