I started out moving for a Cerwin Vega system, to the Polks since outpost.com had them dirt cheap, I had the R30's up front, with a CS1 center and R15 surround and surround back, then upgraded to the CS2 center, then got a Velodyne sub. I then got an SVS Sub, and sold off the Polks for the Def Techs I have now since I got a great deal on all of them... I've also upgraded receivers a few times, and now I'm in the process of saving up for a new larger tv... audioholicism is a vicious cycle.
