My budget is in the 2K range. I will be driving the speakers with a Denon 3806 receiver. I am looking to purchase a 5.1 setup for the time being and upgrade to a 7.1 down the road when the ole' budget permits. I am just trying to decide what to do. Sacrifice on the mains and center to get the EP 500 or downgrade to the ep 350 and get a better setup up front.
