Hi everyone, I'm in the market for a new surround setup and I'd like to keep the cost down. Here's what I'm wondering. Is the SBS-01 5 speaker setup without sub, priced at 599.99 worth the money over two sets of Polk R150's (or R15's) priced at 49.99 plus a Csi25 center channel at 69.99 adding up to a total of 170.00 before tax? I was originally planing to go with the Polk setup when I saw the discount thread here but after checking out the portal page and then seeing the SBS-01's I decided I would get some opinions from you guys here before making my purchase. I have'nt found another HT forum with so many knowledgeable members so I value your opinions. Ultimately, is the SBS-01 sound and build quality worth more than 3 times that of the Polk setup?
