this be a great system . now , I be not a serious audiophile , I be kinda just a regular guy look for a good sound system . I read a ton of review for this and all say it be the best bang for the buck . it be 6.1 , not 5.1 , and the receiver have all the input you would ever want . it be well worth it I think to pay the extra one or two hundred dollar for Onkyo quality , the great receiver , and 6.1 rather than 5.1 .  also , I get this from a site call onecall.com brand new for $ 475 no tax no shipping . that be by far the cheapest . Onecall.com be a authorized internet dealer on the Onkyo website so I be not too worried .
