If you have poor room acoustics, there are no standard components that will provide optimal performance. The room acoustics will prevent this.
However, to get close to optimal performance my suggestion would be to acquire a component with digital room correction. I use a Lyngdorf DPA-1 digital preamp (they make an integrated amp with room correction also). In my large weird room I am extremely pleased with its ability to turn my "poor acoustic environment" into a very-good to excellent acoustic space. In my view, it's performance is extraordinary.
Alternately you could spend a ton of money on bass traps and other passive room correction devices that will cost more money and your wife will hate. Best of luck to you.
