At the moment, I have a Samson S700 connected to one CS 20-39. It is not a plus, I have one of the original ones from way back in September of 2001. For now it has proven to work very well in my home theater however after reading Ed's review on the PB2-Plus, I have the itch to upgrade. I was originally going to get a second CS 20-39, however I'm not sure that would satisfy me at this point. Then, I thought about getting Two CS+ 20-39's, however it looks like from Ed's review and many others, that may not even be up to the task of the PB2-Plus. I'm also in a bind as to how much I'd want to sell my original sub and amp for, as I don't know who would buy it over the net and I'm guessing shipping would be a pretty penny. Maybe I could find someone local. Anyway, I had also considered getting two Ultra's with one Samson S1000. Hmmm, so many choices. Any direction or comments?
