I have the 1804 which is rated at 90x6 but I only run it in 5.1. I could upgrade to the 2803 for another $525 CAN. or the 3803 for $935 CAN. with an exact trade in of the $685 CAN. that I paid for the 1804. I am not interested in 6.1 or 7.1, but would it be worth another $525 for the 2803 or $935 for the 3803 even though what ever amp I use I would be using it in 5.1. The 1804 is 90x6, the 2803 is 90x7, and the 3803 is 110x7. Remember I only need 5.1 so I need to know if the upgrade is justified. I have heard other people going from 90 watts a channel to 110 watts a channel and they were dissapointed. If you were spending your own money would you upgrade. By the way I have a Paradigm PW2200 v2 which is very good in music and HT. If I listen to my movies at -5db under reference do I need to upgrade. Only give me advice if you were going to part with your own money. Thanks in advance. I appreciate all comments.
