The Marantz will be more set it and forget it , where as the pioneer will allow you to tweak to your hearts content. Hopefully someone more familiar with the pioneer will chime in . The Marantz will have the ability to set the front and rear low pass filters separately ,im not sure if the pioneer has the same . I feel you would be more than happy with either one. I have a Yamaha (RX-A1000) and a Denon (3311) and both are great recievers. My Suggestion is the download both manuals and read through and see which one will suit you better and if you find things you don't understand completely come back and as specific questions.
