So I am looking to move to a new AVR and go with a integrated one so I can sell my 5 channel Carver & interconnects and simplify everything. I am pretty well locked in on the Pioneer SC-75 or SC-77. While I like the 68 & 79, they are simply out of my price range and in this instance I am going to buy new from a authorized dealer to ensure I get a full warranty as the warranty on my Integra has saved my bacon 3 times so far.
In looking at the datasheets for each model the differences between the two are below. Here is where I need some help from you guys. Do you think any of those are something I should take into serious consideration in choosing one over the other? I am 90% sure my room is larger than 2000 square feet, but I also dont know if that point alone is worth the increase in cost between the two units. Also if needed I can keep my Carver M1.0t for my LSi 15's to give the system more umph, but would prefer to move that upstairs if possible. Keep in mind there is a decent price gap between these two units (~400 dollars).
I am most curious about the Full Band Phase Control/Auto Phase Control Plus & the Transformer differences.

Any help here MUCH MUCH MUCH appreciated.

DSD Direct Playback via USB Memory Devices (5.6 MHz, 2.8 MHz)
Full Band Phase Control/Auto Phase Control Plus
During multichannel playback, LFE (Low-Frequency Effects) signals as well as low-frequency signals in each channel are assigned to the subwoofer or other the subwoofer and the most appropriate speaker. At least in theory, however, this type of processing involves a group delay that varies with frequency, resulting in phase distortion where the low-frequency sound is delayed or muffled by the conflict with other channels. With the Phase Control mode switched on, this receiver can reproduce powerful bass sound without deteriorating the quality of the original sound (see illustration below)...
The Full Band Phase Control feature calibrates the frequency-phase characteristics of the speakers connected. Standard speakers designed exclusively for audio use generally reproduce sound with the divided frequency bands output from a speaker system consisting of multiple speakers (in case of typical 3-way speakers, for instance, the tweeter, the squawker (midrange), and the woofer output sound in the high-, middle-, and low frequency ranges, respectively). Though these speakers are designed to flatten the frequency-amplitude characteristics across wide ranges, there are cases where the group delay characteristics are not effectively
This phase distortion of the speakers subsequently causes group delay (the delay of low frequency sound against high-frequency sound) during audio signal playback. This receiver analyzes the frequency-phase characteristics of the speakers by calibrating test signals output from the speakers with the supplied microphone, therefore flattening the analyzed frequency-phase characteristics during audio signal playback1 - the same correction is made for a pair of left and right speakers.
This correction minimizes group delay between the ranges of a speaker and improves the frequency-phase characteristics across all ranges. Furthermore, the enhanced frequency-phase characteristics between channels ensure better surround sound integration for multichannel setting.
