NAD M51 Masters Series DAC - Stereophile Class A+ DAC

This unit is in good condition. There are a few lite marks on the bottom of the unit but nothing I can see elsewhere. The unit is in fully working condition with no issues. The remote and original box are included. This is the best bang for the buck DAC on the market. You'll need to spend many times more to get a DAC that sounds better.

----------------------------------------

Overview:

The M51 is an attractive, full-width D/A converter with a digital volume 
control and useful front-panel vacuum-fluorescent display that indicates input, 
volume status, and sampling rate. It offers AES/EBU, coaxial, optical, USB, and 
two HDMI inputs, as well as analog (one pair each single-ended and balanced) 
and digital (HDMI) outputs. While all of the NAD's inputs can handle PCM audio 
data of resolutions up to 24-bit/192kHz, the M51 converts everything it 
receives to a pulse-width-modulation (PWM) signal at a sampling rate of 844kHz, 
controlled by a clock running at 108MHz.

Stereophile Review: “The NAD had a wonderfully detailed 
and revealing sound," said JI. JA noted measured performance that was 
"almost beyond reproach." Compared to the Auralic Vega, the NAD 
produced a cleaner, leaner, airier, less forgiving sound, said JA, though he 
still highly recommends the M51 as a great value for the price.”
