if i had to guess, you have some issues with your room. it may not fix all your concerns but i am certain it will address some. i also have my stuff in the living room so rather than traditional treatments, i have heavy velvet floor to ceiling drapes, a thick rug and over sized fabric couches. it is amazing what these types of "treatments" can do, especially the drapes.
if it were me, i would start with that type of action before adding or subtracting gear.
