OMA Cast Iron SP10 Plinth System
OMA's new SP10 Plinth System is a single sand casting of hypo eutectic or "grey" iron. Designed to accommodate both the new Technics SP10R motor unit as well as the earlier SP10 MK2 and 3 motor units, this plinth provides exceptional rigidity, mass, and vibration damping properties. The underside of the plinth features a spider web of cast chambers filled with a vibration damping polymer. The cast plinth is precision CNC machined to precisely fit the SP10 motor unit and removable armboards, which themselves are CNC machined from torrefied (thermally modified) Pennsylvania ash wood. Due to torrefaction, the wood is both extremely dimensionally stable and offers superior acoustic properties. Arm boards will accept virtually any tonearm with a spindle to pivot distance of 9" to 12" or longer. Arm boards can be exchanged in under a minute, allowing easy swapping of tonearms. The plinth's feet are fitted with holes for 1/4"-20 hardware and is supplied with basic leveling feet. Available in clear lacquer or black powder coat finish. Shown with Schroeder CB long arm, 282mm effective length. Packages available with Schroeder arms, Soundsmith, Grado, Audio Technica and Lyra, Ortofon or Hana cartridges.
Maximum dimensions- 26 1/8 x 20 3/8 x 4 1/8, weight approx. 110 lbs without motor unit.
