Stereo Power Amplifier

Redefining the State of the Art with Purifi Technology

NAD has introduced some of the most innovative amplifier technology in its nearly 50 year history, starting with the 3020 on through such cutting edge models as the 2200, the 208, and the M2. Now we are making the amazing new Eigentakt™ (self-clocking) technology, recently introduced to the world in the EISA Award winning Masters M33, available to a wider audience with the very affordable C 298. We are thrilled to provide this unprecedented level of performance. In short, a perfect companion for the C 658 BluOS Streaming DAC pre-amp.

Powerful. Efficient. Eigentakt™

Amazing Flexibility

The C 298 may be a basic Power Amp, but we have carefully thought through all the use cases typically encountered to create a rich feature content. Selectable balanced inputs make the C 298 a natural for studio use or connection to High End Preamps and Processors. These inputs include a trim control useful for matching to other components. A line out allows further addition of power on the same channel for additional speakers or subwoofers. Auto-sense with selectable threshold is perfect for automating complex systems or hiding the amp out of sight in a cabinet. We even include a Ground Lug that can be very useful for eliminating ground loops and noise in complex multi-unit systems. Added to all this connectivity is a Bridge Switch that turns the C 298 into an amazingly powerful Monobloc Amplifier. Start with one and add a second C 298 later when you upgrade your speakers.

Getting the Basics Right

It is surprising how many seemingly advanced products in the market today often miss many of the most basic requirements for satisfying performance. Low noise circuits, accurate channel balance, proper input and output impedance characteristics, high overload margins and stability with difficult speaker loads. NAD starts by getting these things precisely right and advances from there. Our line inputs, both Balanced and Single-ended, can accommodate all kinds of analog source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation caused by inappropriate loading of the source device. These are all details you can hear.

Sophisticated Power

NAD has moved away from the old fashioned and very power hungry linear power supplies and Class AB output stages that waste nearly half of the energy consumed producing heat rather than sound. Instead we have developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has created some of the best performing amplifiers regardless of basic design principle. These new designs are very linear over a wide bandwidth and provide consistent performance into all speaker loads, providing a dramatic advance over previous models.

The generously dimensioned power supply easily allows for 185 watts continuous and over 570 watts instantaneous power for short term musical transients. Innovative Asymmetrical Power-Drive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce musical transients without distortion or compression. It can operate with any AC mains voltage from 100v to 240v and provides pure DC power to all the various stages of the C 298. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.

Purifi ‘Eigentakt’ Amplifier Technology

Purifi is a Danish technology company that has brought together several of the industry’s leading engineers to apply advanced mathematical modelling to solve the last remaining limitations of audio amplifiers. While there are many good sounding amplifiers on the market today, Purifi has taken a fresh look at every aspect of amplifier performance and found many seemingly small non-linearities that can make a dramatic difference in the overall sound. This return to first principles has resulted in a stunningly simple approach to some remarkably complex problems. With features and technology unmatched by other amplifiers in its class, the C 298 amplifier is an easy upgrade for any system and a surprising partner for the most sophisticated and advanced loudspeakers on the market.

Can be effectively used as a working tool for the predictor (not just for investments)
Format: Hardcover
This is one of the best works on the declining economy and US, associated possible revolution/civil war and later major power war, that is presented in a clear, convincing and replicable way. Kudos to Dalio!! More importantly, the contents of the book can be used to predict upcoming events rather than just perceiving the world on fire with several likely upcoming breakouts (e.g., war with China over Taiwan, the likely loss of our reserve currency, the unsustainable and uncontrollable burgeoning national debt which grows by a trillion USD every 100 days). The author makes a valid case that significant events are moving very rapidly and, for the rest of the 2020s, things are going to get a whole lot worse for the non-elites in our society. Of note, the book was actually written in 2020, published the next year, which then allows the readership now in 2025 to verify the accuracy the observations and predictions. Right on target!

Great book for understanding how the world works!
Format: Hardcover, Format: Hardcover
Dalio has a unique perspective on the topic of the changing world order. He is a successful businessman who has spent his career analyzing economic trends and patterns, and this book is a culmination of his findings. His writing is clear and concise, making complex economic concepts easy to understand. One of the best features of the book is its organization. The book is broken down into 14 chapters, each focusing on a different aspect of the changing world order. Dalio starts with the big picture, examining the major forces driving the changing world order, before delving into the specifics of each major empire, including the Dutch, British, American, Chinese, Soviet, and Japanese empires. Ultimately, he brings everything full circle by discussing the changing world order today and what the future may hold. Another great aspect of the book is the way that Dalio weaves history and economics together. He doesn't just present economic theories in a vacuum; he uses real-world examples to show how they have played out over time. For example, in Chapter 5, he discusses the Great Depression and how it shaped the changing world order in the 1930s and 1940s. He also uses the rise of populism in Chapter 7 to illustrate how economic inequality can lead to political instability. Overall, I would highly recommend "The Changing World Order" to any intelligent human interested in economics, history, or politics. This book is a must-read for anyone who wants to understand the forces shaping our world today and what the future may hold. As Dalio himself puts it, "understanding how the world works is essential if you want to accomplish your goals and live a fulfilling life." Here are some key takeaways from the book: The changing world order is driven by three major forces: the changing relative powers of countries, the changing relative productivity of countries, and the changing values of countries. The rise and fall of empires is a natural part of the changing world order. Each empire has its own unique characteristics, but they all follow a similar pattern of rise, peak, and decline. The post-World War II order was built on the idea of free trade and cooperation between nations. However, this order is now under threat due to rising nationalism and protectionism. China is currently on the rise and is likely to become the world's dominant economic power in the coming decades. However, although this rise is not guaranteed, and there are many challenges that China will need to overcome, the US needs to step up its game on several fronts to compete. The future of the world order is uncertain, but there are a few things we can say with some degree of certainty. For example, the rise of automation and artificial intelligence is a hot topic today likely to have a major impact on the global economy in the coming years. Overall, "The Changing World Order" is a well-written and informative book that is sure to appeal to a wide range of readers. Whether you're a history buff, an economics nerd, or just someone who wants to better understand the world we live in, this book is well worth your time. As Dalio himself says, "The more you know, the more you'll understand, and the more you'll be able to make informed decisions about your own life." Five stars from me, give it a read!

Format: Hardcover
I took Jeffrey Sachs's Globalization class on EDX Academy and somehow stumbled upon this book in between class and finding books around the subject. I watched his youtube video that generalizes the book and was blown away by how my current class I was taking aligned with it. This book is an easy read, and especially for those who aren't well-versed about world history and world economics. I will admit that I do love history, and am learning economics, so this book was a beautiful way merge all these timelines together. The book breaks down and summarizes key points in world history and economics to make points to get the message across each chapter. Font size is great! Might even be considered larger compared to other books. The only thing I wish this book provided was thicker paper in the physical book itself, especially for the hardcover version. If Ray Dahlio ever comes out with a special edition of this with a higher quality paper, I would gladly purchase it for my collection.
