Summary: UPDATE 9/12/2013: I have moved this to the master bedroom as I miss being able to connect ALL my A/V equipment as I could on my Yamaha and experience ALL the different sound fields to enhance their use. I also missed the multiple sound fields assignable to my gaming that my Yamaha offered. Given the price and LIMITED features I am lowering my rating to 3 stars at it's full list price.
Summary: I bought this receiver a few months ago. The first thing I noticed was that the sound wasn't very full with my 5 channel speaker system using the Marantz's built-in speaker tuning Audessy EQ. I changed the settings manually, and got back to the fuller sound I was used to from my old Panasonic slim receiver (which had no EQ). I've run into two other problems, one fairly major, and one more minor.
