Ortofon MC Diamond

Overview

The Ortofon MC Diamond is the flagship of Ortofon's moving coil range, representing the Danish maker's most ambitious statement in phono cartridge design. Its defining feature is a diamond cantilever, chosen for its exceptional stiffness and low mass, paired with a nude Ortofon Replicant 100 diamond stylus. Together these deliver reference-level resolution, speed, and fidelity to the signal cut into the groove, tracing complex passages with clarity and composure.

As a low output moving coil design, the MC Diamond generates a small signal that requires a high-quality phono stage with a moving coil (MC) input, or a step-up transformer feeding a moving magnet input. This is a deliberate engineering choice that keeps moving mass low and preserves the fine detail the diamond cantilever is capable of resolving. The cartridge is built to Ortofon's highest tolerances and is intended to sit at the top of a serious analog system.

The MC Diamond is for the listener assembling a reference-grade turntable and phono chain who wants the finest transient response and micro-detail Ortofon offers. It rewards a stable, well-damped turntable and tonearm, and a phono stage capable of loading and amplifying a low output moving coil cleanly.

How the MC Diamond Compares

Ortofon MC Diamond vs Ortofon MC Verismo

The MC Verismo sits one step below the MC Diamond in Ortofon's reference moving coil lineup and uses a nude Replicant 100 stylus for outstanding detail and precision. The MC Diamond advances the concept with a diamond cantilever, further lowering moving mass for even faster transients and finer resolution. Both are low output designs that need an MC phono input, so choose the Verismo for reference performance and the Diamond when you want Ortofon's ultimate expression. See the Ortofon MC Verismo.

Ortofon MC Diamond vs Ortofon MC Windfeld Ti

The MC Windfeld Ti is a reference moving coil cartridge with a nude Replicant 100 stylus and a titanium body structure, offering a refined and full-bodied character. The MC Diamond distinguishes itself with its diamond cantilever, prioritizing the very lowest moving mass and the most immediate transient speed. Both need a quality MC input; the choice comes down to the character and level of resolution you are after. See the Ortofon MC Windfeld Ti.

Ortofon MC Diamond vs Ortofon MC 90X

The MC 90X is a high-end moving coil reference designed for exceptional accuracy and a natural presentation. The MC Diamond takes the same low output moving coil philosophy to Ortofon's flagship level with its diamond cantilever and Replicant 100 stylus for the greatest speed and micro-detail. Both require an MC phono stage and suit serious analog systems. See the Ortofon MC 90X.

Recommended Turntable and Phono Stage

The MC Diamond is a low output moving coil that needs a stable, high-resolution front end and a phono stage with a moving coil input. Build around a reference turntable and a capable MC phono preamplifier to hear what this cartridge can do.

• Luxman PD-151 MKIIB Centennial A precise, well-damped turntable and tonearm combination that provides the stable platform a flagship cartridge like the MC Diamond demands for clean tracking and low noise.
• Yamaha GT-5000 A massive, rigid deck with a low-resonance chassis and quality tonearm, well matched to the mass and resolution of a reference moving coil cartridge.
• Luxman E-07 Phono Preamplifier A dedicated phono stage with a moving coil input and flexible loading, giving the MC Diamond's low output cartridge clean, quiet amplification to preserve fine detail.
• TEAC PE-505 Phono Amplifier A fully balanced phono stage with adjustable MC loading and gain, ideal for extracting the detail and dynamics of a low output moving coil like the MC Diamond.
• MoFi MasterPhono A high-resolution MM/MC phonostage with extensive loading options, a strong match for dialing in the MC Diamond's low output moving coil signal.

Frequently Asked Questions

Is the Ortofon MC Diamond a moving coil or moving magnet cartridge?
It is a low output moving coil (MC) cartridge, the flagship of Ortofon's moving coil range.

Does the MC Diamond need a special phono stage?
Yes. Because it is a low output moving coil design, it requires a phono stage with a moving coil (MC) input, or a step-up transformer feeding a moving magnet input.

What is the output voltage of the MC Diamond?
It produces 0.2 mV at 1 kHz at 5 cm/s, a low output typical of reference moving coil cartridges.

What stylus does the MC Diamond use?
It uses a nude Ortofon Replicant 100 diamond stylus, chosen for reference-level resolution and groove tracing.

What makes the diamond cantilever special?
A diamond cantilever is extremely stiff and low in mass, which supports fast, accurate transient response and fine detail retrieval.

What tracking force does the MC Diamond need?
The recommended tracking force is 2.4 g. Set this accurately with a calibrated stylus force gauge.

What load impedance should I use?
The internal impedance is 6 ohms, with a recommended load of greater than 10 ohms. Consult your phono stage's MC loading options.

How much does the MC Diamond weigh?
The cartridge weighs 10.5 g, which should be considered when balancing your tonearm.

What is the channel separation and balance?
Channel separation is 27 dB at 1 kHz and channel balance is 0.5 dB at 1 kHz, supporting precise, stable imaging.

What is the frequency response of the MC Diamond?
The frequency range is 20 Hz to 20 kHz, with a response of plus or minus 1.5 dB across that range.

Can I use the MC Diamond with any turntable?
It performs best on a stable, well-damped turntable and a quality tonearm suited to its weight and compliance. A reference-grade deck lets it reach its full potential.

How does the MC Diamond compare to the MC Verismo?
Both are reference moving coil cartridges with a Replicant 100 stylus. The MC Diamond adds a diamond cantilever for even lower moving mass and faster transients, sitting above the Verismo in the range.

Is the MC Diamond suitable for mono records?
It is a stereo cartridge. For mono LP records, Ortofon offers dedicated mono cartridges designed for that purpose.

Do I need a step-up transformer?
Only if your phono stage lacks a moving coil input. A step-up transformer feeding an MM input is an alternative to a dedicated MC phono stage.

What compliance does the MC Diamond have?
Its dynamic compliance is 9 um/mN, which helps guide the choice of a compatible tonearm.

How long does the stylus last?
Stylus life depends on cleanliness, tracking accuracy, and use. Keep records clean, set tracking force correctly, and have setup verified to preserve the stylus.

Can I mount the MC Diamond myself?
Careful setup is possible for experienced users, but precise alignment, tracking force, and loading are essential for a cartridge of this caliber. Professional installation is recommended.

Does the MC Diamond come with a warranty?
Yes, it carries a 1 year parts and labor warranty from Ortofon for the original owner when purchased from an authorized dealer.

What phono preamplifiers pair well with it?
Any high-quality phono stage with a moving coil input and flexible loading works well. Options in our catalog include the Luxman E-07, the TEAC PE-505, and the MoFi MasterPhono.
