Every AVR I have ever used has a section in the menu that outputs level-setting tones to individual speakers, and has a trim setting allowing for the levels to be adjusted. Sure, when you use this...

Perhaps the section in the Guide titled "Using REW to Set or Measure Speaker Levels", starting at page 94, would be useful? This method is considerably more cumbersome than using a test disk with...

I recall a previous post that said a Line-level input (not the Mic input) must be used. Sorry if that previous post was yours as well. Since my laptop has no line-level input, I guess this means...

That is essentially the procedure I used. When you determine the AVR trim in step 2, and if you run an Audyssey calibration afterwards, you have a balancing act to accomplish: the trim that...

I actually have my Oppo connected in two ways. I use an HDMI cable to one input on the pre-pro, and RCA audio cables to the 7.1 input on the pre-pro. This way I can select what processing I want by...

The 7.1 inputs are a pure analog path, bypassing the D/A conversion required by Audyssey room correction, bass management, etc. The reason you paid a premium for the 105 is because of its superior...

I have to admit, with my sub trim at -5, and knowing a trim of -4.5 is the .9V threshold, I am feeling pretty good about the results. And the sub channel sounds really good. Here are some...

Regarding mixing balanced and unbalanced connections, is there anything wrong with using balanced connectors for seven speakers and retaining the unbalanced connection to my subs?

So let me see if I understand your suggestion. I would re-run the calibration, and re-measure to see if anything changed. If nothing changed, I just wasted my time, except that if I ever swap out...

If you recall, I measured .9V with the AVR sub trim at -4.5. I tweaked the sub gains so that the Audyssey calibration results in a sub trim of -5, which provides a bass level at the MLP of 75-76dB,...
