Stogi Ref 313 VTA
Twelve inches of reference-grade precision with on-the-fly vertical tracking adjustment.
The Stogi Ref 313 VTA is a masterclass in mechanical engineering, designed for the listener who refuses to compromise on geometry or set-up precision. By pairing a 12-inch arm tube with a dedicated, reference-grade VTA tower, it allows for seamless, on-the-fly vertical tracking adjustments without sacrificing the structural rigidity essential for accurate sound reproduction.
Sitting at the summit of the Stogi gimbal range, this model incorporates advanced ceramic ball bearings and a unique hexagonal-locking detachable headshell. These elements ensure that the convenience of setup is matched by an unwavering commitment to mechanical stability and vibration control.
Sonically, the Stogi Ref 313 VTA provides a presentation of immense scale, authority, and fluidity. The combination of its extended length and micro-adjustable VTA results in a soundstage that is both deep and wide, with a remarkably low noise floor that reveals the finest textures and spatial cues within a recording.
