VPI periphery ring clamp
訂價約USD 600,好像是VPI盤專用

The Periphery Ring Clamp greatly improves the performance of VPI turntables by flattening the outer edges of LPs, increasing the cartridge’s tracking ability, removing resonance and aiding detail retrieval. A massive ring designed to sit just outside the lead-in groove, the PeripheryRing Clamp's weight flattens the record onto the platter, eliminating edge warps and more completely coupling the record to the platter.
