Here is my situation: I have a JBL sub that the amp broke, basically I think the sub is worthless now. I really do not have enough money right now for the SVS 25-31PCi that I want ($570). But right now I could get a JBL NSPii set because I have no surrounds or rear surrounds yet. And I have the chance to buy a Samson S700 amp for my main speakers (JBL N310). BTW, my receiver is the Pioneer VSXD811S. So it is: A). Wait and save up for a SVS 25-31PCi ($570) or B). Buy JBL NSPii ($230) and a Samson S700 ($250). or C). Just buy the JBL NSPii Do I really need a Samson S700 for my JBL N310? Thanks for any input.
