For me I found Stillpoints SS worked well on heavy components (75 lb integrated in my case) and not so well on lighter components. I tried 3 and 4 SS's under my DAC and my transport; and I could barely tell a difference over some Stillpoints brass cones.... the SS's actually made the sound a tad dry and less involving. Wave Kinetics A10-U8's worked way better than either these; which is what I settled on. I had all three at the same time, so I was able to compare them directly. Also tried the SS under my speakers and they didn't work so well there either, but I blame my thick carpeting.
