Full product details
The C355BEE is the latest in NAD’s range of affordable, yet very high performance Integrated Amplifiers. Building on the strengths of our highly acclaimed C352 (winner of What Hi-Fi Amplifier-of-the-Year and the Hi-Fi Choice Gold Award among many others), the C355BEE boasts many upgrades and refinements taken directly from the highly acclaimed NAD Masters Series M3 Amplifier. These include the application of Bjorn Erik Edvardsen’s innovative and patented Distortion Canceling Circuit in the output stage and BEE Clamp in the power supply. An improved tone control circuit and revised PCB layout has reduced distortion and noise to unprecedented levels. Taken together, these improvements mark a sharp upturn in performance that simply must be heard, to be fully appreciated!

A Closer Look
Features:
The C355BEE is fully remote controlled and comes supplied with the NAD SR 6 system remote control. The remote control features an ergonomic form, with large buttons that are differentiated by shape and position, to make operation intuitive and enjoyable. The SR 6 will also operate many other NAD products such as CD players, tuners, etc.
Flexibility is another NAD strong point. The C355BEE has 7 line inputs (including 2 tape in/outputs with dubbing facility) and the pre-amplifier section can be separated from the power amplifier for easy upgrades or adding ancillary equipment. Thus the C355BEE can be expanded to meet future system needs. The C355BEE sports 2 pre-amp outputs: Many systems benefit from the use of multiple power amplifiers for “Bi-Amping” (using separate power amplifiers to drive the bass and treble section of a loudspeaker). With the second Preout 2 facility an extra power amplifier, such as NAD’s C272, which has identical amplification factor (gain) as the C355BEE’s power amp section - is easily connected. This output can also be used to connect a powered subwoofer, an increasingly popular option.
For remote on/off switching of ancillary components in a system, such as power amplifiers or active speakers, the C355BEE is equipped with a 12V-trigger system. When switching the amplifier on, the 12Vtrigger output is also activated which in turn can activate a 12V-trigger input and switch on the remote devices. Besides the 12V-trigger, the C355BEE also has rear panel IR in and out and an RS-232 port to allow interface to advanced home automation systems. In fact, NAD is a ‘certified partner’ with AMX and Crestron, leaders in the field of home automation guaranteeing compatibility with these systems.
It is fashionable to omit tone controls nowadays: However, provided that the tone controls are properly designed, they can be really useful tools in making improvements to the overall sound. The C355BEE tone controls only work at the frequency extremes leaving the critical mid-band essentially unaltered. The tone control circuits can be completely bypassed by using the tone defeat switch. The C355BEE also incorporates NAD’s acclaimed switchable “Soft Clipping” circuit, which significantly reduces the risk of damage to loudspeakers due to prolonged high power operation.
Design: PowerDrive™
The C355BEE also benefits from NAD’s proprietary PowerDrive circuit topology, now well established and used throughout the NAD product range. The PowerDrive topology allows the C355BEE to deliver maximum performance under virtually any circumstance, independent of the loudspeakers it is driving. The circuitry automatically senses the impedance characteristics of the loudspeaker and will then adjust its power supply settings to best cope with that specific load. PowerDrive topology is a practical approach for enabling an amplifier to easily deal with musical dynamics and difficult speaker loads. Thus we have the highly desirable characteristics of high dynamic power and low impedance drive capability in one affordable package.
NAD also takes a stand against the meaningless “brochure power” touted by many of our competitors by offering Full Disclosure power specs. We specify minimum continuous power, across the entire audible range of frequencies, at rated distortion, for both 8 and 4 Ohms with all channels driven simultaneously. Perhaps even more importantly, we also specify Dynamic Power at 8, 4, and even 2 Ohms, which better describes the way the amplifier will perform in the real world, with musical signals and reactive loudspeaker loads.
Less Distortion = More Music
Noise and distortion mask the fine details of a musical recording robbing musical texture and dimension and replacing them with non-musical artifacts. NAD has spent the last 35 years perfecting our designs to have the lowest distortion and highest power in its price class. This cannot be overstated! Our competitors often rate distortion at only 80% of rated power, and even then can’t match our very conservative spec of 0.03% at any frequency within the range of human hearing. At 80% power our distortion drops to 0.005% or less. Our noise spec is often 10dB (100 times!) less than that of competing amplifiers. This is far from trivial. However, even the most carefully reported specs cannot fully describe the sonic performance of an amplifier. Only your own ears can finally judge our achievement. We urge you to listen and compare NAD to other products in its price range, and even higher. We don’t think you’ll find anything that comes close to offering the C355BEE’s overall musical satisfaction, well-rounded performance, and stellar value for money.
