I have the Stingray. I have played it on Tekton Katz Meow, Tekton Lore, my home brewed 2 ways, and Wilson WP 8s. All but the Wilsons are pretty easy 8-ohm loads and the combos sound very good. On the Wilsons - 4 ohms and I suspect some serious impedance/phase swings - not such a good match even though they are 92 db (or close to that).
I have heard Sonist several times and always liked them. They're being an easy load I would expect them to sound great with the Stingray.
