Easily adjustable for flawless tracking

Fine tune your tonearm to optimize cartridge performance. OA3 Pro’s dial counterweight allows you to set tracking force without a stylus gauge. And its adjustable anti-skate uses a hinged weight to apply consistent force across the entire record surface.

Precision engineered from the inside out

OA3 Pro’s upgraded gimbal bearing allows the tonearm to move with exceptional freedom. Both the bearing shaft and housing are machined from stainless steel and threaded for highly precise axial preload. This means less resonance in the tonearm and near-frictionless movement across the record.

Pinpoint speed accuracy

Theory features a DC-powered sine wave generator system that monitors and adjusts speed thousands of times per second. Our advanced motor controller utilizes a crystal oscillator to drive the ultra-quiet motor with pinpoint accuracy. The result? Minimal wow & flutter and no motor noise during playback.
