C 275BEE

Stereo Power Amplifier

When it comes to an NAD product, the utmost attention to detail is paid, which can be clearly seen in the likes of the C 275BEE. From the heavy gauge steel chassis to the advanced power supplies and copper buss bars, the C 275BEE represents all that NAD stands for. Equipped with NAD’s ATOLogic circuit, which includes both a 12V-trigger system and signal-sensing power-on option, this extra level of flexibility makes it easy to integrate the C 275BEE into any control system. The C 275BEE also benefits from NAD’s proprietary PowerDrive™ circuit topology, which allows the C 275BEE to deliver maximum performance under various circumstances, to even the most powerful of speakers. Delivering a well-rounded, mesmerizing performance, the C 275BEE will let you hear your music the way it was meant to be heard.

Tons of Power for Every Situation

The C 275BEE boasts many upgrades and refinements taken directly from the highly acclaimed NAD Masters Series M3 Amplifier. These include application of Bjorn Erik Edvardsen’s innovative and patented Distortion Canceling Circuit in the output stage and BEE Clamp in the power supply. A carefully engineered 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!
