True Sound Works Apogee Diva Ultimate - Any Good?

The Divas certainly have "a sound". They are along the road of impressionist, especially lower midrange and into the bass, than literal sounding.

They have that "airiness" of open back speakers, but a softening on transients that is just there no matter what. Since they have highs, and play sine waves nicely, folks like to argue the softening, but it's in the transients that they don't have the speed that some other speakers do have.

If you play mostly the music they are good at, and don't need the ultimate "truth" from a speaker, they can be very enjoyable, musical, easy on the ears. If you need a cymbal to have the snap of the real thing, a high hat to sizzle, a snare to POP, you may be disappointed.

This is no knock, they are better than most speakers made today.

I did not stick to the OP well, in comparing the Divas to only those you listed. I would pick the Divas. The Divas have more "substance" (not talking about tonality, talking about density of sound) than the Soundlabs, and the dynamics you list are hardly the best in the dynamic worlds.
