I don't know why many folks don't seem to get this, but all strings start out at their brightest. Fairly quickly, they lose some of that initial brightness, and then for a good long while, they are fairly stable at a reduced brightness - they are getting duller, but VERY slowly. At some point, they will become dull enough that you decide it's time to change them - they don't really "die", you just decided one day they aren't what you want any more.
So, given that life cycle, if you put strings on that are "just right" at first, unless you have a deal with unlimited free strings and a roadie to change them every day, YOU HAVE BOUGHT THE WRONG STRINGS!!!. If that is your initial reaction, in not too long, when the initial zing dies out, you'll be running around telling everyone that "those strings die fast". No, they don't "die fast" - you bought the wrong strings.
The right strings, when you put them on, are too bright. You turn down the tone controls on your bass and your amp or pedalboard, you play them for a while, and then....a week or two later, you turn the knobs back to their normal positions, and... the strings sound great. Congratulations! You have bought the right strings - by buying strings that are too bright initially, you now have the benefit of enjoying that long, relatively stable period, and the strings sound good for a good long time.
I never play a gig with new strings - I always make sure they get played at least a week before I play a gig (this means I need multiple basses (reason #42 for why you need another bass). That way, I am never trying to coax the sound in my head out of a bass that is too bright - if you end up in that situation, you tend to play timidly, which is not a good thing.
Anyway, the short lesson here is: When you try the right strings, you won't know it for a while - you need to leave them on long enough to have them settled before you know if you've go the right strings. If they sound too dull or just right when you first put them on, however, you know you don't have the right strings.
