Annoying clunk/rattle in steering

Hmmmm . . . All good ideas, indeed. But all my front suspension components are new, and the disc brakes are new also. BUT, I will check everything over the weekend, including the possibility of a loose caliper, but I don't think that's it.

The noise seems to use the steering column as a "conduit" for telegraphing the sound into the cockpit. So, I feel it's a steering-related issue although I will try to keep an open mind.
