Surface Plate as Stand Opinions

Well I'm about to buy a 18"x24'x3" granite surface plate and stand for my HP-19. My floor is nice and solid. Those with first hand knowledge chime in please with you positive or negative comments. I have a couple of days before I can go pick it up, so bring on the opinions.


FWIW, I would never use stone, glass (melted stone), or metal under a TT. It rings. I would choose wood which can absorb vibrations as well as allow some transmission to another absorbing materiel underneath the wood. Sure looks pretty though.
Newbee's response is consistent with the experience of many on the Teres owners' forum. There's more to resonance control than just mass and rigidity. I haven't tried stone myself, but only because many who have ended up preferring other materials that provide superior dampening of vibrations.
Hi Dave,

Any hard and rigid material will store unwanted mechanical energy (vibration) and release it over time as extra energy into the chassis of the component. This will contaminate the signal flowing through the component and make it impossible to faithfully reproduce the original instrument as it has been captured in the recording. Other materials that resonate (wood, acrylic, etc.) are also not appropriate for use as a vibration control device as they too will impart their own sonic signature on the signal.

Another issue with using any rigid coupling (a slab of rigid material, a rigid foot, etc.) is that the component will then be in direct connection with all of the unwanted vibration in the floor trying to enter into the bottom of the component. It will also allow any sympathetic vibration of the rack and shelf support (sourced from air-borne vibration) a direct path into the component.

Decoupling the component from floor-borne vibration and providing a method to convert the unwanted mechanical energy into benign thermal energy is the most effective method to address ALL of the sources of unwanted vibration.
