I found the Audio Technica AT605 feet to be well-adapted to my Linn LP12. They are large enough to fit the corners of the plinth well, they compress enough but not too much, they handle both vertical and horizontal vibrations and they are easily height-adjustable. They cleaned up the sound for me a lot, even though I had the TT on a Target wall shelf. These feet are hard to find because they are not made any more, but they do come up from time to time.
