I am running a Marantz 7200 Receiver with Paradigm Reference Studio 80s. I dont think they are being pushed enough and am going to add an amp. Here are my questions: 1. The amp a decide on is that amp power added onto the Marantz power or is it seperate: In other words in my Marantz is giving me 105 and my seperate is giving me 100 am I using 205 or just the 100 from the amp? 2. Is about 200 wpc what I need? I am looking to go the 2 channel route. 3. And lastly, how about some suggestions for amps that you all think would be a good fit for me? Thank you so much. Price wise I am in or around the $400-$600 range for a good used one.
