Ortofon OM 5S Cartridge

The Ortofon OM 5S is a high-output Moving Magnet (MM) cartridge designed for listeners who want clear, musical sound with maximum durability. Featuring a Spherical stylus profile and the signature Optimum Match (OM) body, this cartridge is engineered to perform beautifully on almost any turntable. It is particularly adept at playing vintage vinyl and worn records, providing a smooth, consistent sound that minimizes surface noise.

The OM 5S is defined by its warmth, stability, and punch. It offers a very musical and coherent sound with a strong midrange that makes vocals stand out. It provides a "safe" and enjoyable listening experience that focuses on the heart of the music rather than clinical detail.

KEY FEATURES

• Spherical Stylus Profile: The OM 5S features a polished Spherical diamond. Because of its rounded shape, it is less sensitive to alignment errors and sits higher in the record groove, making it much more forgiving on older or slightly scratched records than sharper needle profiles.
• Optimum Match (OM) Versatility: The cartridge features a removable weight plate in the mounting bracket. Keep it in for standard tonearms, or remove it to reduce the mass for low-mass tonearms. This unique design ensures the OM 5S is compatible with nearly every turntable ever made.
• Robust Construction: Designed for longevity, the OM 5S is built to handle the rigors of daily use. It is a favorite for those who are just starting their vinyl journey or for secondary systems where ease of use is the priority.
• High Output (4.5 mV): The efficient generator system delivers a strong, punchy signal. This ensures excellent compatibility with any standard MM phono stage or integrated amplifier, providing a vibrant and energetic sound.
• Easy Stylus Upgrades: The OM series is famous for its "building block" approach. When you are ready for more detail, you can easily upgrade to a Stylus 5E, 10, or 20 simply by swapping the needle—no tools or re-mounting required.
