I am totally new to the audio world and am trying to put together a home theater system. Chances are that I am getting a Onkyo 705 receiver, Monitor Audio S6 or PSB Image T55 for the floors, same brand surrounds, and a Paradigm PS-1200 sub.

Here is the embarassing question....... do I need an amp for this system? Does the receiver do anything to drive the speakers (built in amp)? I would really like to push the speakers if I would like to but I do not know if the speakers that I have selected have enough ability to take advantage of an amp.

There are other things I do not understand such as a pre-amp and biwiring, but we'll stick with the basics for now!

Thanks in advance!!
