I chose the easy way out for my full size, 185 lb. speakers using spikes. I have a custom listening room with 12" thick, steel rebar reinforced, 3000 lb psi poured slab. At least no vibrations are going from the floor up, possibly only the speaker itself vibrates. I like Townsend platforms and springs, possibly for my next speaker.
I use the Townsend Seismic Sink (bladder) for two decades under a VPI TNT VI+ turntable. Without it, I would have junked the table as it has poor vibration control with those fancy feet.
For the rest of my equipment, I use various versions of Stillpoints (ultra-minis, SS) and they work great after testing out a dozen others (some were equally good, most worse, none better). I also use a buckwheat pillow under an EAR 324 phono preamp and CD recording/editing machine (better than anything else, inelegant and very inexpensive). The buckwheat pillow is rather good overall; however, I wouldn't use it near my tube equipment (heat).
