Himiguel, I wish I could say that there is no benefit of them under your speakers and amps, but I cannot deny that they are amazing. I know a guy with more than 60 of them! The problem under components such as a phono stage is that the Fives are so big, you have difficulty getting them under them.
If you have a StillPoints Rack, there is a replacement coming for their acrylic shelves that allows using the SP Ultra SSs that is every bit as good as the Fives and way better than the acrylic shelves which hide the real benefit of the SP Rack.
