NAD has a formidable reputation when it comes to integrated amplifiers. The NAD 3020, which is widely regarded as a milestone amplifier; the 310 with its unusual circuit topology offering performance at a price not deemed possible and recently the all new C320, which is taking the world by storm, are some examples underscoring this reputation.

The C300 is Erik Edvardsen’s latest amplifier design, partly a continuation of the C320 and a redevelopment of the 310. The C300’s pre-amp circuit topology is virtually the same as that of the award-winning C320. Whereas the 310 used a combination of MOS-FET and Bi-polar output stage, the C300 uses an entirely MOS-FET output stage.

Although the C300 takes the place of the 310, it can’t be viewed as a direct replacement. The superior performance, remote control, component quality make it even better value-for-money than the 310 is, even if it’s at a slightly higher price-point.

Features:

The C300 is remote controlled for the most important functions: Volume and mute.

Flexibility is another NAD strong point. The C300 has 7 line inputs (including 2 tape in/outputs with dubbing facility) so will not run out of inputs easily. The headphone socket will drive virtually any non-electrostatic headphone.

It is fashionable to omit tone controls nowadays: However, provided that the tone controls are properly designed, these can really be a useful tool to make improvements to the overall sound. The C300 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.
