Korf Audio is a manufacturer specializing in the development and production of high-precision tonearms for analog playback. Founder Alexey Kornienkov follows a strictly engineering-based approach: Every design decision is based on mechanical, geometric, and material considerations – not on sonic ideology or tradition.

Precise storage: optimized separately horizontally and vertically.

A key feature of Korf tonearms is the consistently implemented bearing design for horizontal and vertical movement .
For the horizontal axis , highly precise, backlash-free ceramic ball bearings with extremely low friction are used. They allow absolutely free movement of the tonearm along the groove modulation and ensure precise guidance with minimal starting torque – essential for exact channel balance and low distortion.

The vertical support is implemented using flexure pivot bearings. This type of bearing has virtually no friction and therefore almost no breakaway torque.

This ensures that the needle remains stable in the groove even with complex height modulations and high dynamic peaks, without unwanted micro-movements or bearing resonances.

The clear separation of the two axes minimizes mechanical couplings, cross-resonances and energy losses – a crucial advantage over simplified bearing concepts.

Materials: Stiffness, damping and stability

Korf Audio also follows a clear technical concept in its choice of materials. Depending on the model, the tonearm tubes are made of high-strength stainless steel, ceramic, or sapphire to achieve an optimal balance of stiffness, mass, and internal damping. The goal is not maximum damping, but rather a controlled energy flow without uncontrolled resonance spectra.

Models such as the TA-SF , TA-AF , as well as the TA-SF9R and TA-SF11R Series II are exemplary of this approach: technically sober, precisely executed and completely designed for low-distortion and low-resonance sampling.

Conclusion

Korf Audio caters to analog enthusiasts who understand a tonearm as a precision mechanical instrument . The combination of sophisticated bearing technology and clearly defined material selection makes Korf tonearms tools that consistently unlock the potential of high-quality cartridges – neutrally and with control.
