Bad Vibrations

With the stylus sitting on a stationary record, a wrap to the sides of my sandbox is completely damped out, but a downward wrap along the top perimeter edge of the sandbox is transmitted through the speakers. A wrap to the steel rack below the sandbox is also transmitted through the system. Transmission of vibration was reduced but not eliminated by cutting up the sandbox plinth.

My next moves include marble or granite plinth material, and replacing the sorbethane sandwich in the TT suspension with solid material such as maple, brass, and springs. From there I might try a Machina Dynamics Promethean platform, which uses several plinths separated by springs and points to achieve resonant frequency of 2hz. The sandbox can be floated on the platform or eliminated.
