UA-103TI
prototype
“A huge coup!”
Knut Barnstorf, ANALOG 03/2025
Our UA-103TI MC cartridge is based on the proven design of the DENON DL-103, whose LC generator serves as the starting point for a new technical development. The internal resistance has been adjusted to 13 Ω to optimize compatibility with standard MM phono preamps. The housing is individually manufactured using 3D printing from titanium or aluminum, resulting in a weight of 32 grams (including the headshell) with high rigidity and minimal resonance. Boron is used for the stylus cantilever, fitted with a MicroRidge stylus designed for precise tracking of the groove. An adjustable coupling system also allows for fine-tuning of the mechanical parameters to adapt the tracking behavior to different tonearm systems.
The cartridge is designed for use with a variety of tonearms and can be used in both lighter and heavier systems. The design is currently in the final phase of visual refinement, while the technical design has already been completed. Series production will begin shortly.
