I own a great pair of Paradigm Studio 40s and I have a nice Paradigm subwoofer as well. I am going to connect them to a new Pioneer Elite VSX 33 that is on its way. I am simply looking to create a 3.1...and.... ....I would like to add a Center Channel Speaker but not for what a matching Paradigm CC590 costs ($900). I have heard great things about Polk's CS-20 Center which is much cheaper. Can anyone advise me on what I can add on as a Center without it being an awkward transition from Fronts to Center. Thanks so much!
