In the last couple of months I have upgraded my entire system (almost). My current setup includes Denon 3802, M50s up front, VP150 center and QS4 surrounds. The only piece I have not upgraded is my sub (Sony WM40). I think the sub sounds okay but I have been reading quite a bit on the SVS subs and the rave reviews owners have given them. I have had my eye on the 25-31 pci, but I am wondering how much improvement can I expect from upgrading my sub? Anyone who owns an SVS sub please give me some feedback. I want to know if I am really missing out on this aspect of my system.
