I'm looking for opinions on whether or not to replace my sub or upgrade my center channel. Here is my situation: My sub (PSB Subsonic 6i) has been without it's amp for quite some time. Twice I blew it's electronics before the fuse protected it. So...at the moment, my sub is being powered by an old Kenwood Pro Logic receiver (that is the only thing the receiver is powering). Certainly not an ideal situation. I'm looking at the HTD Level 4 sub which is currently on sale. Specs for that sub can be found at . My center channel is working fine. It's a PSB Century 200ci. I'm craving a new cetner channel that has more of a range than the 200ci does. I'm looking at the PSB Image 9C. Link to the specs of the 200ci is . Link to the Image 9C is I can't get both at the same time. I have to make a choice. Any suggestions on what should come first? FYI. My fronts are PSB Image 2B's and my receiver will be the new H/K AVR330.
