FWIW, as I've never actually heard either CDP (but I do have the 128 purchased on the 6moon reviewers recommendations) SE has reviewed the Droplet as well as Consonances' 'lesser' unit, the 128 and the 168. From these reviews you should be able to envision the differences.
I can assure you of one thing, my humble 128 (using different tubes than those provided!) is very dynamic. Excellent bass, extended highs, very transparent, and never less than musical. It is very tunable for good system matching. I'm sure the 168 might be a tad better, but from my recall of the 6moons review, it was not much more than a tad.
