Speaker suggestions for saround sound.

Hi everyone I am currently looking to put a home theatre/ second two Chanel system in my basement, I have a used Cary sli-80 integrated amp for my left and right speakers. And a Yamaha av receiver for the other three Chanels. I found a deal on a totem forest souround 5.1 speaker setup for 2000$ all in on Craigslist. Or planing to go monitor audio gold 5.1 seytem. Or a B&w 704 s2. What would be a better option.
