There are a lot of Decware Amp owners there with lots of experience with different speakers.
FWIW, I have tied a single Decware Zen Select with a couple of different speakers that I own and did not have good results. A single Zen Stereo amp likes a very low impedence load like nom. 2 Ohm. It didn't work well at all with my highish effeciency 8 ohm speakers.
I can say that I have heard the Zen sound absolutely great in a couple of my friends systems.
Decware makes several different amps. Maybe the Integrated or Torii would work better with the Coincident speakers.
Anyway, ask the experts at the Decware Forum. You will get an answer.
Enjoy,
TIC
