Need some help...

I am setting up my 6.1 home theater surround sound.  I have a Denon 2308 receiver, 5 nanostat speakers, and the Omni S8 sub. I am looking to get a center channel speaker and was wondering if the Nanostat center channel or the Omni V2 center channel would be the best fit.  Obviously, the nanostat center channel was designed to complement the nanostat satellites, but I have heard the Omni V2CC produces better sound quality.  Please advise.

Thanks
