Key Features
- An improved engine, which provides a high level of sonic accuracy.
- Spherical diamond that is perfect for playback of 78 rpm shellac records, which require a larger stylus profile.
- The cartridge body is manufactured from Hopelex, an environment-friendly material which ensures high rigidity while eliminating unwanted resonances.
- 2M 78 uses a strapped output to deliver the same output signal from both sets of pole pins. This effectively eliminates the need for mono-specific equipment, making it possible to enjoy true mono reproduction on any stereo playback system.
Ortofon has optimised the design for ease of mounting the cartridge, and the weight and size to fit the most common turntables on the market today. The 2M Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.
The 2M Series is Designed for Precise and Accurate Retrieval of the Information in the Record Groove
The 2M Series is developed in conjunction with the Danish Industrial designer Møller Jensen Design – the same designer who designed the award winning MC Jubilee and Kontrapunkt series. Inspired by the facets of a diamond, whose contours gracefully trace the grooves on a record’s surface, the 2M’s handsome elegance establishes a great combination of form and functionality.
The name 2M was selected from among several ideas. We wanted a modern name that would be easy to pronounce and remember, and therefore an alphanumerical name was chosen. 2M means MM, which is the abbreviation for moving magnet.
Of course the 2M isn’t just another pretty face. It has been engineered to the highest standards and is congruent with Ortofon’s unrelenting commitment to providing the most precise and accurate reproduction possible without coloration.
Summary of the five classic variations of 2M Cartridges:
- 2M Mono SE, 2M Mono and 2M 78 are a true mono cartridges for playing mono vinyl records
- 2M Red is an all-purpose cartridge that delivers open, dynamic sound with a slight touch of warmth
- 2M Blue adds more dynamics and resolution, sounds more open and reproduces more details
- 2M Bronze adds even more details and resolution but in a very even handed way that pays respect to all elements
- 2M Black is the best of everything, true to the groove with resolution and accurate insight into each recording
The 2M series of cartridges features Ortofon’s trademark split pole pins, an invention that enables moving magnet cartridges to have a flat frequency response, as with a moving coil cartridge. Split pole pins were invented by Ortofon, and were originally presented in the 500 series and OM Super series.
We have optimised the design for ease of mounting the cartridge, and the weight and size to fit the most common turntables on the market today. The 2M Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.

Powerful and especially so read aloud by the author.
Format: Audio CD
Hearing this powerful book read by Dr Tyson made it doubly understandable and enlightening. I needed to hear the experience, hurt and anger expressed so incredibly honestly and with the power of his emotion. I saw the CDs here at a reasonable price and I am so much more aware hearing rather than reading this book. Dr Tyson teaches powerful historic and current systemic racial experience such as every white person will do well to encounter. If you want to learn more than you already know, listen to these CDs on Black experience from Dr Tyson. Could be disturbing to anyone who does not want to learn the truth he teaches. It’s so packed with truth I will listen to it more than once more. Thank you, Dr Tyson.

brilliant, painful
Format: Hardcover
Timely, provocative, brilliant, painful, and, ultimately, a very necessary step toward authentic national healing and transformation. As a white, long-time fellow traveler, I am so grateful that Dr. Dyson has answered his calling to lead us toward redemptive justice with truth, decency and love--albeit, at times, necessary tough love. I am in my third read already and learning more and more each time.
Dyson's sermon serves as an exceptional read for believer and non-believer alike as it offers a framework and lexicon for us to engage with one another as we work our way through ongoing racially turbulent and polarized times. I am not a critic by trade so I will leave the professional analysis to the experts. I am a K-12 educator and seeker of social justice. I found this work both accessible and challenging in the best of ways. In my daily work, the evidence of the invention of whiteness, white innocence and white fragility and their pernicious impacts are ubiquitously abundant such that Dyson’s claims simply cannot be denied.
Dyson’s sermon is not always a comfortable read. That’s the point. It is a workout for the soul and psyche that results in the growing pains necessary for personal and collective liberation.
Thank you, Rev. Dr. Michael Eric Dyson, for opening your head and heart so broadly and deeply there is room enough for all of us in this racial healing process. The writing of this book is the ultimate act of truth and forgiveness. You have entrusted us with your most profound insights, personal experiences, and extend a vulnerability that humbles and arrests me. As you shared in a recent interview, "your trust in us grows out of forgiveness and the demand for truth for which is stands on, and the love it seeks to extend". Amen! I am in!

A MUST READING FOR ALL OF WHITE AMERICA! A HELPFUL BRIDGE TO UNDERSTANDING THE CHASM IN RACE RELATIONS BETWEEN BLACKS AND WHITES. WRITTEN IN A MANNER AND FORMAT MOST PEOPLE CAN ACCEPT AND UNDERSTAND.

I AM A PERSON OF COLOR AND I WILL DEFINITELY SHARE THIS WITH MY WHITE FRIENDS WHO SOMETIMES UNFAIRLY GET A BAD RAP FOR BEING WHITE.

Powerful, challenging, and inspiring. An essential read
Format: Hardcover
This is a book that I challenge all my white friends to read, no matter where you stand on the spectrum of confronting white privilege and systemic racism. Michael Eric Dyson delivers a powerful, engaging, personal, informational, inspiring sermon that’s essential at this moment in time when racial division is especially high.
I urge you to read with an open heart and mind, to set aside your discomfort and listen to Dyson’s plea for white Americans to reckon with the harsh truths of racism.
Dyson is an ordained minister, so what better way to present this than as a sermon. He divides it into multiple sections: in “Hymns of Praise,” he cleverly shares hymns in the form of rap lyrics; in “Scripture Reading,” he quotes Martin Luther King Jr.; in the main sermon, he addresses whiteness specifically (including white innocence, white fragility, and white privilege) and then segues into a section about what it’s like to be black in America. Following that is “Benediction,” one of my favorite parts: in it he offers practical suggestions for what white people can do to make things better.
The whole thing is incredibly current and topical, with commentary on Black Lives Matter, the recent election and Donald Trump’s rise to power.
For white people who seek to understand more about racism and white privilege in America (and really, that should be all of us), this is the book to read. It was literally written for us.

Best book I’ve ever read
Format: Hardcover
I had to read this book in grad school and it changed my life. I have recommended it countless times and given it as gifts to many family members. Dr. Dyson explains racial concepts in easy to hear language and specifically targets white folks. As a white person, I have learned so much from Dr. Dyson through this book. I believe every white person should read this book.
I also had the privilege to hear Dr. Dyson speak at my university, and his spoken words and written words carry the same passion and energy. Truly this book is one of a kind.
This book really is a sermon to white america, I doubt most people of color would gain as much from his words. Dr. Dyson uses mostly black and white language, and addresses issues about whiteness and how it permeates our society and upholds racism. Anyone could read and enjoy this book, but white folks (especially the white people who don’t think they’re racist) need to read it.
