The Les Davis 33 1/3D Record Slipmat use the same technology and materials used for the very successful 3D-2 isolation pads. Using constrained layer damping technology to suppress in room vibrations the 33 1/3D is placed between the turntable’s platter and record allowing the stylus to operate with far less vibration. We have a 33 1/3D on demonstration so please pop in and hear the difference for yourself!
