Fade, I agree with most of the reply's you've already received in this thread and your problem is most likely a tuning issue. How do you have your M50 mains configured..(large or small)? I think the general concensus of people on this board would recomend a "small" setting so that all the low frequencies are sent to the sub. If you do decide to upgrade the receiver though, the main thing the 3803 has over the 2803 is a feature called video uplink which means if you run your video signals through the eceiver, you can elect to have it convert coaxial and/or composite signals to component video signals and only run 1 cable (component video) to your TV/monitor. I have the 2803 and am very happy with it's featues and performance. Again, play with the tuning of the speakers first though.
