Sota Sapphire VI Turntable
American-Made Suspended TurntableA turntable must address and resolve all of the issues that affect ultimate performance, if it is to achieve the goal of bringing you closest to the musical experience. The basic goal of achieving maximum information retrieval in turntable performance is one of controlling microscopic vibrations - a task that requires the utmost in engineering precision and comprehensive design.
The design objectives of Dynamic Stability (the control of forces present in a dynamic system), Environmental Isolation (the control of forces from "outside" the turntable’s world), Easy Set-up (guaranteed results in all situations), Control Over Vinyl Resonance and Variations, (which would otherwise undermine the performance of even the best turntables) and Control Over Power Line Impurities (which are present in all installations and result in sonic anomalies if not controlled), are all addressed in the design of the SOTA line of precision turntables.
The SAPPHIRE™ features the traditional four-point spring suspension. A new SERIES VI SAPPHIRE™ would also include our I-Clamp record clamp.
