In Reply to: Granite, and other materials that ring or resonate should be avoided... posted by Barry Kohan on November 25, 2004 at 14:30:47:
If you have a reference to a rigorous mechanical analysis of the energy bouncing around a turntable system to support your claims, I'd love to read it.I doubt your reasoning with respect to granite. Thicker granite may be difficult to damp, but the thicker it is, the less need there is for damping. Damping is simply mass loading: why mass load an already-massive base.
I have trouble accepting the idea that vibrations from the stylus will travel into a massive granite sink only to be reintroduced back into the cartridge. The energy is dissipated as heat within the various crystaline minerals in the granite, never to be heard from again.
My current thinking is that the spaciousness and realism of LP playback (including a lack of digital's pinpoint imaging, also lacking in real performance) is an artifact of delayed reflected energy. This energy bounces around the arm and possibly plinth and platter in a low-mass system, and is reintroduced into the cartridge and ultimately interpreted by our brains as a reverberant sound field. The spectrum of the reflected energy may cause some of the false detail artifacts you mentioned, but I suspect it contributes mostly to the ambience. Again, any analysis that covers energy transfer would be appreciated.
