I had the super heavy weight. Sold it for the Star Sound Technologies (now Live Vibe Audio) platter ground.

In A/B testing, the Platter ground had a more open sound. A little bit of splitting hairs, but the difference was there and I didn’t pay much for the platter ground.
Both weights fall into the category of nice to have vs must have in my mind.
For the record, we also tried the audio points under multiple pieces of gear. I didn’t feel that made an improvement over the UD feet. However I was legitimately surprised at the difference they made under the amp. I didn’t buy them for the amp, but I still kind of wish I had.
