No, they aren't.
DTs are generally favored by HT folks, I almost never see music listeners praising them. My guess is, that's because the DT sound signature is often described as "bright" with a smiley-shaped EQ curve, which many people enjoy for movies but less commonly for music especially midrange-heavy genres. They are somewhat similar to SVS Prime speakers in this regard.
Music listeners usually prefer "neutral" or sometimes, "warm" speakers.
~ Are you a "geek hobbyist" obsessed with squeezing out that last 5-10% improvement? The economy will thank you...especially the Chinese one. Or are you more of a get-set-and-forget "casual user" who simply wants to increase your enjoyment of movies, TV and gaming? Relax, HT isn't rocket science, nor does it have to cost an arm and a leg---especially if you ignore the aforementioned vocal minority. And remember to smile...it's just a silly hobby, after all. :)
