STOCK CLEARANCE – PRICE REDUCED
Used only for 400 hours for demonstration. Almost like new. Stereophile A+ recommended component (2012-2014) NAD’s technology uses a very powerful processing engine that operates at much higher speed and with much greater accuracy than typical DACs. Running at 108MHz, the M51 resamples the incoming pulse code modulated (PCM) signal and converts it to a pulse width modulation (PWM) signal with a sampling rate of 844kHz. Operating in a differential mode with double precision, the M51 has state-of-the-art specifications for low noise and freedom from distortion. The extreme headroom afforded by the 35-bit architecture allows for a DSP-based volume control that does not reduce resolution. M51 is also a fully functional digital preamp with seven digital inputs and one of the world’s best volume controls. As a ‘preamp’ it is totally noise and distortion free because all switching and volume control is done in the digital domain. There are no analogue circuits except for the Class A buffer at the output of the DAC. While input selection is available from a front panel control, volume can only be selected via remote control.
