Different subwoofer settings for different albums?

Undoubtedly the low bass in some recordings is more pronounced than in others and the desire to get up and make sub adjustments is hard to resist!
I`m sure that most people starting off with sub`s do what I did and run them too loud. In my modest experience that tends to subdue the rest of the frequency range especially the highs. 
The best setting is where you can notice how much better the overall sound is make when listening with and without them even though their contribution sits in the background. 

Not my experience.  If a Clapton album was mixed so that the bass and drums are down in the mix a little and the focus is on the guitar, that's what you're "supposed" to hear and a sub(s) won't accentuate that if you have your levels set correctly.  If Deamau5 wants to make your liver quiver with the bass, then your subs should do that at the same settings.

Oh man.  Oh man oh man.

Subwoofers integrated correctly are glorious. 

If you find yourself raiding their gain, you probably didn't set them up correctly, and should consider actual tone controls.

Well integrated subwoofers are invisible. Find a different dealer.

Set your sub or subs properly (not by ear in my book) and forget. The sound recorded is what I'll listen to, and with three subs down to 25Hz I'll only hear what is on the program, nothing more or less. Having that clean tight ultra-low last octave adds a lot, but only when it should. Mine are 100% sonically invisible.

If I have a recording that is just too lean, or being played too low in volume, I can use a 'loudness' type button to help add a subtle bit of low end curve. I use it for low volume listening mostly. I never touch the subs once dialed in.
