NAD's PowerDrive Circuit has been proven to offer a remarkable combination of high current drive needed for complex loudspeaker loads, and high levels of undistorted dynamic power. By monitoring the precise operating condition of the power amplifier, PowerDrive uses this intelligence to automatically optimize the power supply settings for uniformly low distortion and maximum power in the real world of music listening. The powerful 603 S2 Anniversary Edition combines the accuracy and transparency of our acclaimed Continuum mid-range cone with the scale and authority of two dedicated bass drivers.
