I sold my Clearaudio ring a long time ago for reasons which Nil so aptly has described above, was however curious to try the TTweights ring which is made of copper not stainless steel and chose Larry's heaviest version for on my Goldmund Reference I with excellent results. All the advantages and none of the drawbacks Nil has described and which I had experienced before with the Clearaudio at more than double the cost. Don't ask me why this is so. Probably lucky in hitting on a good synergy between ring and TT. Never thought the sound of the Goldmund, which I had already heavily modified, could be improved that much. But there you are.
