Infinity HT vs. Boston Acoustics HT

[bdr98]

I am a newbie here and appreciate all the information I have found searching through the various forums. I would like any feedback on these two systems or if I am missing another brand that is better for the same price. I am finishing my basement and my family room is basically 20 x 17. I am using in-ceiling speakers for the rear surround to keep everything clean. The LCR will be placed in built ins. I will be powering the system with the Pioneer 1016-TSXV. I will be using this system for HT poruposes 80% of the time. I have narrowed it down to the Infinity and Boston Acoustics systems. I have also put together a Polk, HTD.com and JBL system that fall into this price range but I keep coming back to these two. Thank you....
