I'm looking into purchasing from B&H the JBL 7.1 kit for $1000

(JBL JBL Speaker Kit, Consists: Center EC25, Pair of Bookshelf E10, 2x Floorstanding E100 and Powedred Subwoofer E150P - Beech)

and to accompany that possibly the Yamaha RX-V1500 7.1 a/v reciever

My question is this: is my head screwed on strait?
