Like several of the other posters, I may choose slightly different things to emphasize, depending on the content, and on my own mood. A couple of people noted that they don't max out their volumes all the time. With me, it's partly a matter of the mood that I'm in. Some days it's fun to really let it rip with loud volumes and low bass, and on other occasions I might be content with lower volumes and less low bass.
As SBuger noted earlier, the listening volume can affect the equilibrium between mid-bass and ULF, due to the way our hearing works (the Equal Loudness Contours). So, for instance, if I leave my subs at the same +15 setting when I am listening at -10 MV, and at -15 MV, I will hear relatively more ULF at -10, and relatively more mid-bass at -15, because we hear mid-bass frequencies more easily than we do lower ones. Depending on what I'm in the mood for, I may just raise or lower my master volume to change the acoustic balance in the way I want it for that particular movie or mood.

Changing gear and placement of subs can disrupt that balance and while you may increase both quantity and quality of your system in doing so, you simply may not like it as much due to it feeling different. Then, over time and after tuning the new setup, you can get to a point were you may like it better.
I've always felt this way. My perceptions of my system can change from day to day, or even from song to song (or movie to movie). It's all about what mood we are in. People laugh when they see all my bass curves (haha, and rightly so) for my mini 2x4 but that's why I have them, because what I want isn't set in stone.
Some days I swear that music in 2 channel is better and why would I ever use the upmixer... and then the next day it's the opposite. Some days I want my chest to feel every kick drum even at lower volumes and the next day it's annoying. Ok, rarely is it annoying but it does happen.
Bottom line, as long as we have a system that is capable of playing content back how we want/when we want it and we are set! The trick is we need to have enough time tinkering to find out all these different preferences to match our mood.
