NAD C298 Stereo Power Amplifier (OPEN BOX)Sale!
OPEN BOX NOTE: This unit is 100% “as new”, lightly used for demonstrations.
With an impressive 185 WPC, and 4 ohm stable, the NAD C298 can easily drive even the most demanding loudspeakers. In bridged mode the C298 delivers 620 watts into a single channel. Purifi Eigentakt™ technology nearly eliminates harmonic and intermodulation distortion and allows for an even, wide frequency response with negligible output impedance. It’s not often that such novel audiophile technology is made available with so much value packed in.

The C 298 may be a basic Power Amp, but NAD has 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. There is 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. The NAD C298 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.
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 NAD developed even better performing circuits based on switch mode power supplies and Class D output stages. 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.
