Know before you buy
Yes, as a low-output moving coil cartridge, the AT-OC9/III requires a phono stage capable of handling MC inputs. You will need a preamp that provides approximately 60 dB of gain and supports a load impedance of at least 100 ohms.
The AT-OC9/III offers significantly better focus, imaging, and dynamic range than typical moving magnet cartridges. It provides a warmer, more forgiving tonal balance, making it an excellent choice for listeners who want high-fidelity detail without the clinical harshness sometimes found in other MC designs.
Absolutely. Its forgiving tonal balance is specifically tuned to handle older pressings well, helping to minimize surface noise while maintaining impressive bass dynamics and presence.
The recommended tracking force is between 1.8 and 2.2 grams. We suggest starting at the middle of this range and adjusting based on your specific tonearm setup and listening preferences.
While the cartridge will perform well out of the box, it requires a break-in period to fully settle and reach its optimal sonic potential. You may notice the sound opening up and becoming more refined after several hours of playback.
Yes, VTA adjustment is recommended for this cartridge. It is best to perform a final VTA calibration after the cartridge has completed its initial break-in period to ensure the most accurate playback.
