My mains are Paradigm Studio 20s and my center is also a Studio 20. I couldn't be more pleased with sound integration. I started out with the appropriate Studio center (don't remember the model number) and felt it did not mate with the 20s they way it should, not to mention the fact it was freaking hugh making placement problematic. I returned the center and had the dealer order me a single 20. I works great, much better to my ears than the purpose built Paradigm center.
