I don’t have the Cary yet, maybe Monday. Current speakers are Magnepan 3.7i with a Hegel H390 integrated.
I'll try the Cary, but I'm afraid it won't be up to the task.
86db/4 ohms? Maybe not, but still, in push-pull 40 wpc triode, I do not think that you need as judicious with efficiency as you would need to be if you were buying speakers for a 15 wpc SET rig.
