NAD C 298 amplifier, 570 watts of instantaneous power
The C 298 is a two channel powerhouse that is a perfect partner to high quality preamplifiers or in any application where additional channels of audiophile amplification are desired. Traditional with all NAD components, the C 298 represents exceptional value offering performance, features and technology unmatched by other amplifiers in its class. The new NAD basic amplifier is a compelling upgrade for virtually any advanced HiFi system and its robust power with upgrade flexibility will drive the most sophisticated and advanced loudspeakers on the market.
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, the company has 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 340 watts continuous into 4 ohms and over 570 watts instantaneous power for short term musical transients. Asymmetrical PowerDrive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce musical transients without distortion or compression.
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 found many seemingly small non-linearities that can make a dramatic difference in the overall sound. The Eigentakt modules are manufactured by NAD under license from Purifi, allowing NAD to optimise these specifically in combination with the custom designed power supply and input stages of the C 298. The C 298 ($1,999 U.S. MSRP) will be shipping in October 2020. ■
