a sound foundation

This substantial this 24-pound turntable attenuates external vibrations by utilizing what Michael Fremer notes is “an unusually heavy, multi-layer and well-damped chassis as well as large, viscous-elastomer damped height-adjustable feet and a 4 pound, elastomer-damped… aluminum platter”.

ready to play

Stealth is a 3-speed direct drive turntable that comes complete with an s-shaped tonearm, a detachable headshell, and a  factory-mounted, precision aligned Ortofon 2M Blue cartridge.

An auto-stop feature turns off the direct-drive motor at the end of a record.
