IT-407 SS
An impeccably refined 12-inch dynamic balance tonearm for absolute acoustic transparency.
The IT-407 SS stands as the ultimate expression of the Ikeda tonearm lineage, meticulously crafted to provide a neutral and highly stable platform for the world’s finest cartridges. As the top-tier 12-inch model, it builds upon the legendary IT-407 architecture by introducing a more advanced material composition and refined internal signal path, ensuring that every nuance of the groove is captured with surgical precision.
The design of the SS model is focused on the mastery of resonance. While the exterior is finished in polished stainless steel for exceptional rigidity, the internal structure combines aluminium and brass to effectively damp unwanted vibrations before they reach the signal path. This meticulous approach to construction results in a tonearm that feels both substantial and effortlessly precise in operation.
Sonically, the IT-407 SS is defined by its authoritative low-frequency stability and exceptional resolution. By utilising hybrid 6N and 4N copper wiring and rhodium-plated contact points, the arm achieves a level of transparency that allows the character of the cartridge and record to emerge without coloration. It is a commanding instrument for the audiophile who demands absolute composure and spatial accuracy from their analog system.
Key Features
01
Stainless steel exterior
High-rigidity stainless steel housing provides excellent resonance suppression and structural integrity.
02
Hybrid copper wiring
Internal signal path utilises a high-quality blend of 6N and 4N copper stranded wire for pristine conductivity.
03
Rhodium-plated contacts
All critical contact points are bright rhodium-plated to ensure long-term oxidation resistance and signal purity.
04
Precision internal damping
Combines aluminium pipe and brass within the arm tube to meticulously control internal mechanical resonances.

Design & Philosophy
The IT-407 SS is engineered to be a state-of-the-art transcription tool. By moving beyond the standard material choices of the CR-1 model, the SS version focuses on the elimination of micro-vibrations through a sophisticated layering of metals, creating a tonearm that is remarkably inert and tonally balanced.

Build & Materials
Every unit is hand-assembled in Japan using premium alloys. The rotating assembly features high-precision bearings housed in brass to ensure the lowest possible friction, while the hybrid copper wiring reflects a commitment to minimizing signal loss from the cartridge headshell all the way to the output terminals.

Sonic Signature
This tonearm is celebrated for its imperturbability. It excels at tracking densely modulated grooves and presenting a soundstage with significant depth and substantive scale. The bass response is notably stable and clear, providing a rock-solid foundation for the midrange and high frequencies to resolve with complete freedom from harshness.
