DeVore Gibbon 8's or Salk Songtowers?

I have enough money in the budget to try one more pair of speakers before calling the whole thing done for another twenty years. Emphasis is on quick, snappy, detail-oriented sound with excellent image, but still silky enough through the mid and treble so as not to overwhelm my slap-happy room. Power is McCormack DNA-HT5, pre is McCormack MAP-1, interconnects by Blue Jeans, power and speaker cables by Element.

If the two finalists are the DeVore Gibbon-8 and the Salk Songtowers (with the previously stated objectives in mind), which pair is the better choice? It's impractical for me to audition either pair before buying and trying.
