It is my opinion that the higher a speaker's quality, the more revealing it is, and the more important becomes the quality of what's on that little disc that goes into your DVD/CD player. As long as there is no mixing and mastering standard to which each disc must be held, some discs are going to sound better than others.
Axioms are very accurate, revealing speakers and some discs will NOT sound good on them. But, the majority will sound exceptional. Lesser speakers, like your JBLs will tend to level things out, rendering the "UGH" factor of a poorly mixed or mastered disc acceptable. But, likewise, they will diminish the "WOW" factor of a fabulously wonderful disc, reducing it to..........well..........only acceptable.
So, with quality speakers, even though some discs will sound "teeth gnashing, fingernail on chalk board, irritating," once you've experienced "goosepimpling, hair raising, breath taking incredible," it's mighty damned difficult to settle for every disc sounding merely "acceptable."
Just my theory.
