IT-407 CR-1
A 12-inch dynamic balance tonearm engineered for ultimate transcription accuracy.
The IT-407 CR-1 is the definitive 12-inch statement in the Ikeda tonearm line, representing the pinnacle of mechanical precision for analog playback. By increasing the effective length compared to its shorter counterparts, this arm provides improved tracking geometry, reducing lateral tracking error and harmonic distortion across the entire record surface.
At its core, the IT-407 CR-1 utilizes a sophisticated dynamic balance mechanism that applies tracking force through a finely tuned spring system. This design allows the tonearm to maintain consistent pressure against the record groove, providing exceptional stability and performance even when encountering warped vinyl or complex, high-energy modulations.
Sonically, the IT-407 CR-1 is defined by its sense of scale, effortless authority, and tonal richness. It imparts a grounded, authoritative quality to the music, allowing for an expansive and highly detailed soundstage. It remains the arm of choice for those who seek the classic, full-bodied Ikeda sound, delivered with the technical refinement and structural integrity expected of modern high-end Japanese engineering.

Chapter 01
Engineering Philosophy
The IT-407 CR-1 is built on the belief that a longer tonearm is inherently superior for transcription. By geometry-optimized design, it minimizes the geometric errors inherent to pivoted arms, allowing the stylus to trace the groove with greater accuracy and less mechanical stress.
