I'm looking for a 3 channel amp to power my fronts and center. (HTD Level 3 Towers) My budget is about 500-600 and i was looking at the rotel 1066 6 channel and bridging it to 3. What are other options in my price range. Can I get a 5 channel, for example Parasound 855 and bridge it into 3. I have a sony 30 es receiver and will eventually get a pre/pro but for right now, I just want some extra power for the front. Thanks.
