MC 90X -
A Classic,
Reimagined. Designed to breathe new life into
your favorite recordings, allowing you to
rediscover the sounds that have shaped your life.
Celebrating the lineage of the iconic MC A90,
the MC 90X is a reimagining of a classic,
combining precision engineering with
advancements in material science and magnetism.
Designed to bring out the depth and detail in
every record, this limited-edition cartridge
builds on Ortofon’s expertise in analog sound
reproduction while introducing improved rubber
dampers and a striking new blue finish. Its
stainless-steel structure, crafted using
Selective Laser Melting (SLM) technology,
provides excellent rigidity and resonance
control.
The Wide Range Damping system, Field Stabilizing
Element, and Ortofon Replicant 100 diamond
stylus work together to capture the full depth
and nuance of even the finest vinyl pressings.
Each cartridge is meticulously hand-assembled
and undergoes rigorous quality control to ensure
an authentic and immersive vinyl experience.
With a richly detailed midrange and extended
frequency response, the MC 90X stays true to the
Original recording, offering a refined listening
experience that continues the legacy of the MC
A90..

Refined Damping System
One of the Ortofon MC 90X standout features is
the Wide Range Damping (WRD) system, which
ensures outstanding linear frequency response
and an extended upperfrequency range. This
advanced system employs a platinum disc placed
between two specially designed rubber absorbers,
providing superior tracking and effective
resonance control across the entire frequency
spectrum. Ortofon’s in-house developed rubber
compounds further enhance performance,
optimizing damping characteristics to minimize
distortion and improve sound clarity. These
innovations make the MC 90X a high-performance
cartridge, delivering exceptional detail,
precision, and an unparalleled listening
experience.
High Precision &
Performance
Achieving linear reproduction with a wide
frequency range and optimal tracking requires a
diamond that closely mimics the Original cutting
stylus. The Ortofon MC 90X features the
Replicant 100 diamond, renowned for its thin,
light profile and exceptionally large contact
surface, allowing it to trace grooves with
unmatched precision. Combined with a special
polishing process and a Boron cantilever, this
design ensures remarkable transparency, speed,
and responsiveness, delivering exceptional sound
quality for an immersive audio experience. At
the heart of the MC 90X is a revolutionary
Selective Laser Melting (SLM) manufacturing
process. This high-precision technique uses
laser-welding of micro particles to create a
one-piece body. This enhances rigidity, reduces
unwanted resonances, and ensures optimal
cartridge mass, resulting in superior sound
quality and performance. For an exceptional
signal transmission, the coil wires are made of
the special alloy Aucurum, a gold-plated 6NX
oxygen-free copper.
