I have purchased a Denon AVR-2803 just a few days ago and have been happy with it but suddenly a problem has cropped up which I cannot fathom the cause. Irrespective of the source, be it DVD or Digital Cable Box, I am finding that I am having to crank up the levels far higher than normal. Before a normal, not loud level at all, on my digital cable box on the music channels used to be -35 or so but now I have to have it at - 20. Similar changes on DVD - I have to have it quite a bit higher. My hearing has not changed in the last few hours - In my bedroom levels have not changed there. I can get high volumes but that requires far higher increases in the volume control than I had to do previously. I am getting worried that something has gone wrong in the pre-amp stage and the levels that are being fed to the amplifier are lower than before. I don't know whether this is some psychological reason pushing me to buy the ARV-3803 (which I think I perhaps should have bought) but I don't think so. Any ideas would be most appreciated. Since this is just a few days old I am not sending this in for repairs - not on. The store I bought it from are I am guessing not willing to swap this for another 2803 but I believe quite happy to upgrade me to a 3803. Peter Edit - PS - I did a reset of the receiver and this has not changed anything.
