I need some advice on purchasing a surround sound system. My new home is prewired for surround sound and I am a virgin to all sound equipment and therefore have only heard BOSE lifestyle at electronic dept stores. The price is steep - $2000, but if i plan to spend this much I want to know I'm getting my monies worth, or should I consider purchasing a name brand receiver and building my surround system. If so are there any good recommendations that are in the price range of $1500-2000? Any help would be appreciated.
