Guide to The Best Sound Equipment for your Xbox 360

Just as with visuals, next generation video games require top notch equipment for audio output, if you're looking for the ultimate experience. And you should - that's why you've gotten yourself an Xbox 360, right? Well, in case your old sound system or the stereo speakers on your TV suck, here's a list of sound equipment you can go for, so you can make the most out of your 360 and the games you run on it.

DEF: Surround sound refers to the application of multichannel audio to channels "surrounding" the audience (generally some combination of left surround, right surround, and back surround) as opposed to "screen channels" (center, [front] left, and [front] right).
