Better sound without additional black boxes. Have you considered room acoustics? That's my first question when people ask me for home theater advice. Your theater's acoustic environment is as important to your system's sound quality as any single component. Sure, you can improve the sound with a new amplifier, new speakers, or the latest and greatest EX/ES processor; however, if your room isn't acoustically optimized, you still won't get maximum performance from your system, no matter how much it costs. Adding acoustic treatment is probably the easiest and most effective thing you can do to improve your sonic environment. Granted, it can be daunting to calculate reverberation times so that you add the right amount of acoustic treatment. Fortunately, Performance Media Industries (PMI) has done the work for you with their CinePanel acoustic-treatment kits.
