NAD 5420

 Compact Disc Player

Balanced MASH One-Bit High Resolution Digital to Analogue Converter:

With CD players utilizing MASH or other one bit technologies, our engineers have found that what really makes the difference in their performance is the care taken in power supply design,, PCB layout, grouding, and selection of analog circuit components

Circuit Simplicity:

Many CD players are "over-designed" with unnecessary stages of analog circuitry that sacrifice transparency and subtle detail. NAD players have just three wide-band analog circuits and only one coupling capacitor in the signal path (bypassed by a low loss film capacitor), thus preserving the emotional detail of the original performance.
