Ortofon MC Rohmann High-End cartridge

MC Rohmann is named after Ortofon’s former managing director, in honour of his many years of service.

This cartridge body is milled from a solid block of aluminium and the dark blue anodized body exploits aluminum’s special damping characteristics to suppress resonance. The slim-line Nude Orto-Line diamond ensures flawless tracking of even the most dynamic passages.

MC Rohmann conveys the full range of detail and subtle nuance, even when a powerful brass section competes with the fine nuances of quieter instruments such as the flute or harpsichord.

A high performance MC transformer or MC preamplifier is recommended. Recommended load: 100 Ohms or more.
