I searched the forum and this was the only thread that shared the same experience. I live in an apartment and my walls are literally slightly vibrating from cars driving in the garage and the all the AC systems being on. I was considering some vibration isolation for my system and was researching the usual suspects like Iso Acoustics and Symposium, however I remembered I had four 1 inch silicone hemisphere from Hudson Hifi just lying around.
On a whim I put them under my Jeff Rowland CS2 Integrated which is on a Salamander design shelf on the ground lifted by blocks, and I can't believe the difference it made. Everything became much more 3D, from violin strings to Tony Bennet's voice, both the low level detail and the highlights of the note got better. It's as if switching to HDR content from SDR on TV. I am pleasantly surprised. Just ordered some more to try on my DAC and streamer.
