Upgrading Spikes on Target Wall Shelf

I have been replacing the points on my equipment with Star Sound Audio Points gradually. So far have them under my REL subs, replacing the stock feet on my Scoutmaster, unthreaded ones under my stand mount speakers and under my components. I have some target stands that I am going to try soon. In every case there was a noticeable improvement.

I have used them both ways and they work both ways but Star says they work better downward and after initially disagreeing with this I have come to the conclusion they are right. But you could try it. The Audio Points are available with their own screws so they would be easy to substitute . Slate works well, I use to use it to make turntable platforms, put deflated racquetball under them, latest thing in 1982. Stan
