Configuring the AV7005 in my system was a very straight forward affair. Setting up the inputs to certain HDMI and digital inputs was very easy, as well as configuring the video processor for each input. One nice feature was the ability to use a web interface from my computer to rename the inputs on the system using a keyboard instead of using an onscreen keyboard, which makes renaming these inputs far easier than usual. Once I had my inputs setup, renamed, and the unused inputs disabled, I went about running Audyssey.
In the past I had always found Audyssey to be a little bit of hit and miss with its settings. Sometimes the distances were pretty good, but sometimes they were off. However, with the recent receivers that I've used, it's been much better and the Marantz is no exception. It did incorrectly tell me that I had one speaker hooked up out-of-phase on my initial attempt, but I re-ran it multiple times and never saw this behavior again, so I'd likely attribute this to background noise or something else that caused an error in the measurement. The speaker distances were nailed down by Audyssey with exacting precision, and I didn't need to adjust any of the settings. It also got the crossover for my speakers correct which was good as the last room correction system I used set it too high, though the position of them has not changed since then.
I went ahead and measured all 8 positions around our couch, using the Audyssey Setup Guide at AVS (link this to: http://www.avsforum.com/avs-vb/showthread.php?p=14456895 #post14456895) as a reference. Once this was complete, a nice feature on the AV7005 was the ability to browse the graphs of the corrections applied to each channel in the system. Typically, most receivers will only show you the crossovers applied to each channel and none of the EQ, but the Marantz let me view this as you can see. You also have your choice of which Audyssey curve to apply (Standard, Flat, Front) depending on how you want the final result to sound and you can see in the images how the different curve affects the EQ applied to the speakers. Overall the Audyssey setup process was very simple and straight forward, as it should be.
One feature that I particularly liked in the menu system of the Marantz is the ability to view exactly what type of data is entering over HDMI, and what data it is outputting. For example, my TiVo HD outputs over HDMI as YPbPr 4:4:4 and the Marantz would output the exact same thing. A Blu-ray player that I had in for review output everything as x.v.Color 4:4:4, even when Deep Color was disabled. For most people this information might not be important, but if you know that your display has issues with certain types of color information, this can be very helpful, and you can read more about this on the bench test section.
