Trickle Down Masters M3
The C 375BEE is far more than a bigger C 355BEE — in fact, it is much closer in spec to the M3 Integrated Amplifier from NAD’s high end Masters Series. It also incorporates an updated version of NAD’s “Building Block” concept to make the addition of the PP375 phono module or the MDC DAC USB Digital Analogue Converter and other affordable future upgrades possible. Attention to the most minute detail is evident everywhere, from the heavy gauge steel chassis to the sophisticated power supplies and copper buss bars channeling almost absurd amounts of current to the custom gold plated speaker binding posts.
The C 375BEE boasts many upgrades and refinements taken from NAD Masters Series M3 Amplifier. These include application of Bjørn Erik Edvardsen’s 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.
Note:
The C 375BEE features two MDC slots in the rear so you can comfortably install both an MDC DAC and the inboard PP375 module. The MDC DAC has a selector switch built into the rear panel that allows you to select the Phono module as required. Some early models of the C 375BEE (prior to serial number H08C375BEEG05870) require a different configuration of adding a DAC by using the outboard NAD DAC 1 instead. We recommend you check with your authorised NAD dealer to find the best option that is suitable for your unit and your needs.
