I've owned a Denon AVR3300 and was really happy with it. IMO it's the best surround receiver that Denon made. I currently own an Anthem AVM20, with aragon amp, and they will bury me with it. I don't think that there is anything wrong with your system.
A few suggestions:
1. Possible hearing loss. As we age we loose some hihg frequency hearing.
2. Change is room furnishings. Moving furniture, floor treatments and wall hangings can change the "sound" of the room.
3. The upgrade bug has hit. This bug can cause major hearing loss and financial ruin. I know when I get the bug, my system sounds like crap.
Good Luck!
