As with every amp in the Classic Series, we here at NAD have carefully thought through all the possible use cases and strategically chosen the most essential of features. Thanks to selectable balanced inputs, the C 268 is a natural mate for high-end preamps and processors. These inputs include a trim control useful for matching with other components, or for use in bi-amping speakers. A line out allows further addition of power on the same channel for extra speakers or subwoofers. On top of all this connectivity is a bridge switch that turns the C 268 into an amazingly powerful Monobloc amplifier.
Getting the Basics Right
As a member of NAD’s Classic Series, the C 268 delivers a richly satisfying sonic performance thanks to its “music-first” features. Accurate channel balance, proper input and output impedance characteristics, and low noise circuits all come together within this one stereo power amplifier. Additionally the C 268’s line inputs, both balanced and single-ended, can accommodate all kinds of analogue source components by offering ideal input impedance traits with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation caused by unfitting loading of the source device.
Having moved away from old fashioned linear power supplies and Class AB output stages, NAD 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 resulted in some of the best performing amplifiers regardless of basic design principle. The overall design of the C 268 is very linear over a wide bandwidth, providing dramatic advances over previous models with consistent performance into all speaker loads.
