U-Turn Audio Orbit Theory Turntable with Ortofon 2M Blue or 2M Bronze

The U-Turn Audio Orbit Theory Turntable is the most advanced turntable ever produced by U-Turn Audio, engineered for audiophiles seeking exceptional precision, clarity, and musical realism. Built around the advanced OA3 Pro Tonearm, the Orbit Theory delivers ultra-low resonance, precise tracking, and smooth, stable playback. Choose between the Ortofon 2M Blue for balanced, detailed performance or upgrade to the Ortofon 2M Bronze for enhanced resolution, lower distortion, and greater groove detail. A grooved frosted acrylic platter, electronic speed control, and ultra-quiet motor ensure consistent speed accuracy, while the solid hardwood plinth and Sorbothane-isolated feet minimize vibration. Each Orbit Theory is hand-assembled and tested in Woburn, Massachusetts for uncompromising quality and long-term reliability.
