WE ARE AN AUTHORIZED NAD DEALER!PREOWNED - $1000 LIST! - FULLY TESTED - INCLUDES ORIGINAL POWER CABLEA remarkably affordable stereo amplifier, the NAD C 268 has features and technology unmatched by other amplifiers in its class. Designed for multiple stereo setups, the C 268 can be used in a variety of scenarios, including traditional stacks with a preamplifier or for bi-amping your favourite loudspeakers. The NAD C 268 is even bridgeable, seamlessly transforming its bountiful output from 80 x 2 to an outstanding 300 watts. Although the C 268 may appear to be a straightforward power amplifier, this Classic Series amp is brimming with rich features that will elevate your system.NAD C 268 Stereo Power AmplifierAmazing FlexibilityAs 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.You can also pair the C 268 with the NAD C 368 Hybrid Digital DAC Amplifier, and with both units bridged for mono, 300 watts per channel of distortion-free sound become available for your listening pleasure. The C 268’s auto-sense feature with selectable threshold is perfect for automating complex systems or for hiding the amp out of sight in a cabinet. Included with the C 268 is a ground lug that is very useful for eliminating ground loops and noise in complex multi-unit systems.Getting the Basics RightAs 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.Sophisticated PowerHaving 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.The power supply of the C 268 is capable of nearly 200 watts continuously and over 500 watts instantaneously, allowing for short term musical transients. NAD’s innovative asymmetrical PowerDrive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce the most demanding music without distortion or compression. It can also operate with any AC mains voltage from 100V to 240V, and provides pure DC power to all the various stages of the C 268. 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.The C 268 uses a customised version of the proven Hypex UcD output stage. This allows for massive power with nearly immeasurable distortion and noise in the audible range. Every detail of this design has been carefully crafted and perfectly executed to wring out ever last drop of performance.AmplifierContinuous output power into 8 and 4 Ohms(Stereo mode)80W (ref. 20 Hz-20 kHz at rated THD, both channels driven)Continuous output power into 8 Ohms (Bridge mode)300W (ref. 20 Hz – 20 kHz at THD 0.03%)THD (20 Hz – 20 kHz)<0.03 % (250 mW to 80 W, 8 Ohms and 4 Ohms)IHF dynamic power (Stereo mode, at 1 kHz 1 % THD) 8 Ohms120W4 Ohms200W2 Ohms250WDamping Factor>100 (ref. 8 ohms 20 Hz – 20 kHz)Input Sensitivity (for 80 W in 8 Ohms)750mV/50kohmsFrequency Response±0.3 dB (20 Hz – 20 kHz)GeneralStandby power<0.5WUnit Dimension (WxHxD) – Gross435 x 100 x 390 mmNet weight7.3 kg (16.1 lbs)Shipping weight8.7 kg (19.2 lbs)

It has been bench tested and found in good working order. Condition: Normal condition for its age. There are a couple of nicks/ Marks/ scratches just normal aging. I did replace all external screws to new ones as the old ones were pitted/ losing their color. Given the fragile nature of these classics, this sale is AS-IS. The amplifiers have been bench tested, re-biased and serviced prior to shipping and found working normally. This is a fully working unit.
