Is an AV receiver + Amp the best solution for me?



My first real audio system currently functions for both a small scale home theater and music listening. I have an Onkyo TX NR626 with SVS prime tower and center, SVS PB 1000 sub, and for surrounds I have Niles in ceiling speakers vshare (7.1 setup). Most reviews I've read recommend a decent dedicated amp for my Prime towers and I'm wondering the best way to get a home theater and stereo experience. I've thought about getting a new receiver with pre-outs and then a dedicated 2 channel amp to better power the towers. Would the receiver do a decent job on the remaining speakers? I'm I'm concerned about leaving the center without an amp.
Thanks for any info.
