Hi Gary

It is my understanding that adding a stereo amp to a home theater system to drive the front L&R speakers has 2 objectives:
1. relieve power reuirements on the other channels, and/or
2. produce a "better" sound for stereo playback of music sources (CD,FM, TT,MP3)by using a "better sounding" stereo amp and/or a more powerful amp.

IMHO, with your system, not much benefit would be derived unless you added something like a 200w x 2 Bryston or Parasound Halo.
