I'm experimenting with the SP-004 today under my Silverline Sonatina II's and I am very impressed (to my surprise). The sound is more articulate and almost SET-like (using Cary SLI-80), bass is tighter and cleaner and deeper. I have carpet and had been using the brass cones that the Silverline comes with, which look very high quality in their own right. So I did not expect this jump in performance from stands. They look good too. Like Dan, I'm using the two points in back and one in front. They are more stable than I had expected, albeit still a worry. The stock points screw in, whereas these points are resting under the speaker via a small brass-like cup.
