Ortofon OMB 20 phono cartridge

ORTOFON OMB-20 OMB 20 OMB20 PHONO CARTRIDGE
- New old stock in plastic case and LP Gear packaging. Screws, nuts, and stylus guard are included.

The Ortofon OM B20 OMB-20 phono cartridge is the version of the OM 20 cartridge offered to manufacturers for their use as original equipment. "B" stands for bulk. Their popularity stems from three reasons: (1) it plays music with authenticity, refinement, and artful competence that makes it forever endearing; (2) it is sensibly priced; and (3) it offers an upgrade path to highest fidelity. By simply replacing the stylus, an Ortofon OMB 20 owner can upgrade its performance to the highly rated Ortofon OM30 or OM40 cartridge.

There is a discontinued Super OM cartridge version. The current 2M is a further extension of this. Both illuminate the high frequencies to make it sound livelier — hotter. We prefer the original OM as it delivers an organic, natural, faithful, and honest sound of the recorded material.

Super Upgradeable
All OM models have the same body, construction, and magnetic circuitry. The only difference is the interchangeable stylus unit. Thus, when your level of musical sophistication improves, you can simply switch the existing stylus to the Ortofon Stylus 20, 30 or for pinnacle performance the Ortofon Stylus 40. The Ortofon Stylus 40 offers pinnacle performance for the most demanding listener.
