I just checked and the model of my center is a Polk T30. I have a few audio distribution units, such as an elan s86a that handles my main audio throughout my home and basically a spare russound mca-c3 connected to some jbl arena bookshelves. I bought the elac debut 2.0 bookshelves at magnolia for 149, have them hooked up to that NAD integrated and jeez, to my ears, they sound really good. The infinity floorstanders look really good, considering I'm coming off a primus line, they should be a substantial improvement? I do want the matching center for any set I purchase.
