Materials

Another method to avoid the high cost of complex electronics and mechanical methods of damping vibrations is careful selection of materials. Rival designs have exploited the unique mechanical impedance of brass and acrylic, but have stopped short. They always compromised: by accidental inversion of these two opposite laminates, or by use of intermediate materials, e.g. sub-chassis and bolt components made of steel or aluminium. Acrylic is optimal for the platter and armboard, and the sub-chassis is a laminate which should be musically resonant brass, as it is on the Quasar. Can you imagine a trumpet made of acrylic? Or a violin/guitar string stops made of brass?
