I want to attach them, not just lay the table on top of them. Opinions? Thank you!

Oops, I missed that part. Since Star Sound has already been recommended, I'm going to assume that the Rega feet are screwed in with metric M6 threads. You can also get M6 threaded brass cones and pointed feet from Mapleshade.
Now here's the fun part: I have some very inexpensive M6 threaded brass cones I got from PartsExpress (sold as Dayton speaker cones available in black, chrome, black chrome, or gold color) for $20 + ship. I've had them on for about 1-1/2 yrs. Recently I found some fairly large diameter metal floorsavers (about 1-5/8", about the smallest that would work in this application) that are made to protect shelves and floors from pointed spikes. I placed these on the suspension rings of a set of Vibrapods and set the points on these Vibrapod+floorsaver stacks. The results were beyond my expectations. It dropped the noise floor, opened up inner detail, all those great things, and this is a very inexpensive solution that makes for a noticeable difference.
If you have trouble finding floorsavers big enough to span the Vibrapods, you could get some brass or acrylic stock 1/8" to 1/4" thick, cut them into 1-3/4" circles, and use a drill press to put a little dimple in the dead center so the spikes position on them properly.
Of course, it's easier if you can just find floorsavers that are big enough for the Vibrapods.
