Granite and digital..

Yes, I have a sense of humor. You should try it sometime. I do not appreciate some 🍑 🎩 interrupting a thread to make some dumb statement. Capish?

Devil’s advocate? I don’t think so. Too mundane.

You obviously can’t tell the difference between your 🍑 and your elbow. Still suffering PTSS, eh? Did you flunk out of school? 

Uh, that’s why it’s a good idea to isolate speakers and subs. Granite’s properties of high mass and stiffness are good for the sound. That’s why isolation platforms from the big boys oft come with granite top plates.

When granite is placed on top of air bladders or springs the presumed ringing of granite is minimized since the granite slab is isolated from the floor right along with the component. It is also fun to build dual layer mass-on-bladder/spring systems to increase isolation effectiveness. I spike the bottom granite slab AND the component on the top slab. Thicker is better since it will be stiffer and better resist bending forces.
