Liked the article, thanks for sharing. Saved. Especially the easy to see bar graph to visually comprehend how it can be thought of. I've always viewed as a window of range and I liked seeing it worded that way.
As with what was discussed with multiple amps (my back in the day car audio) "level" matched with a multi-meter. Same concepts. If say have 4 amps on multiple VC's or sharing enclosures. Each amp measures different AC voltage output for maximum potential. Using the one with the lowest output and back down others to match. Same concept with signal chain devices. Your always limited to the weak link device for the window.
When the article mentions complicating things with EQ etc, that's also referring to +/- levels(and any induced EQ) in the AVR for each channel. Let's say for subwoofer out Wayne's procedure says to max it out so then the volume raised shows maximum number before distortion/clipping. True but the subwoofer setting in the AVR might not be set at that level for the final preference setup which makes the overal volume of the AVR lower. And that setting effects the mains tied to the volume might not reach potential (especially if you have more outboard amps tied to them). I prefer using zero/flat settings in the AVR find max volume then adjusting each one individually to see if there's any trouble pre gain clipping or distortion.
To try and sum; our AVR (at max volume) sub setting is usually at (0 / +3) and can go to +6 before clipping the next device (BFD). At this same volume level for this setup the mains are also within clip range of their respected outboard amps. This way everything is tied and come up together within the max overall window. "edited" to add one thing I've noted is if your AVR channel settings are far from 0 like say +7 or something you can tell there's more main volume probably left of the table. If it's far in the minus like -7 you main volume is probably higher than it needs to be and hot.
Just a quick thought on using the sig gen in REW. I could be completely wrong but my thought process is the signal levels out of your sound card might not be the same as your true source ie dvd player or media pc card. I can see it working well if you have your main media pc running REW from it to setup.
