I have found that the cassettes that have the larger cogs mounted on aluminum "carriers" can get noisier with time. I
think it's because the carrier moves around a bit on the cassette body and when it shifts it makes a crunchy ping. In your case you cure it by removing, cleaning, and retightening the cassette... but once it starts moving again it won't stop.
Try cleaning all the pieces of the cassette again and then reassemble with a layer of grease on the cassette body and between the aluminum carriers. It won't stop the movement, but at least it won't be as noisy about it.
