Product: NAD C 316BEE Integrated Amplifier with Phono
Brand: NAD
Description: NAD's C 316BEE integrated amplifier lived up to expectations, garnering multiple accolades including an EISA award for 'Best Product 2008-2009' and top recommendations from the world's leading audio publications. This sophisticated circuit combines low noise with high overload margins to eliminate noise and distortion. RIAA equalization is extremely accurate (a rarity at this price) and there is even an infrasonic filter to reject airborne vibrations that can cause parasitic feedback. 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. As featured in NAD's top Masters Series models, PowerDrive uses a complex 'analog computer' to determine the optimal settings. All the hallmarks of NAD technology are present, from the generously sized toroidal power transformer and low ESR smoothing capacitors, to the multiple regulated secondary supplies, to the heavy duty discrete output transistors, the C 316BEE is every bit as refined and sophisticated as other NAD amplifiers. With five line-level inputs, an MM Phono Input, full IR remote control, defeatable tone controls, and a front panel input for a phone or tablet, the C 316 is fully equipped to be the control center for a high performance music system. Continuous power is a conservative 40 watts, and dynamic power (more important for music listening) is impressively more than 100 watts! This is far more usable power on tap than other amplifiers at this price, and this power is available across the entire audible band at a class leading 0.03%. We offer a 30 day return period for any reason. Buy with confidence!
