Yes, that Marantz is one good looking AMP!! The heat sinks in the Fosgate are built inside each module. There are 5 separate 200 watt amp modules, and you can reconfigure each channel. Lets say you want to add 2 rear back speakers, then you sacriface one 200 module for a module with 2 100 watt amps, actually you would have to break down 2 modules or you lose a speaker...right? You can configure this thing to have 10 100 watt amps.

Of couse I'm not giving up and any of that head room. That's what they make money for, another 2 channel amp!!
I do like that Marantz though...
