The Prime Signature is the next step up from the Prime, which took the world by storm 2 years ago during its initial release. It features an upgraded JMW 10-3D Reference arm in a “metallic black” gloss finish with Nordost Reference wire. The chassis consists of an aluminum plate sandwiched between a composite material for improved dampening. Due to the additional weight of the table, we upgraded the feet to our Classic Signature feet. In addition, both the motor housing and all Delrin posts and armboards were upgraded to a heftier stainless steel.The TurntableThe vinyl wrapped MDF composite material chassis is bonded with a sandwiched aluminum plate to provide the ultimate resonance control and rejects feedbackThe JMW-10-3DR Tonearm features Nordost Reference WireThe four Stainless Steel corner posts are designed for isolation and mechanical groundingThe 300 RPM, 24 pole, AC synchronous motor is capable of high torque and quiet operation.
