That table is close to 30lbs. I would try Pods first. That is an expensive table but those cone footers, you could actually put one Pod under each one. It will probably be better however to bypass the whole thing and put the Pods directly under the turntable base. Probably the best will be if you can remove the CA feet and replace them with Pods. Probably won't want to mess with that though I am betting. Even though it probably will be the best or certainly the most cost-effective solution.
I would call John Hannant at Townshend. He helped me with mine. Vibration control with turntables almost always comes down to the details of each table and situation. John has a lot of experience with that, which is probably how he was able to help me so much.
