Commentary
A CD player equipped with a noise shaper.
The D/A converter is equipped with a 20-bit noise shaper and a W super linear converter.
The 20-bit noise shaper reduces the requantization noise by feeding back the calculation errors of the 20-bit output of the digital filter. Combined with Denon's unique W Superlinear Converter that eliminates 0 cross distortion, it realizes high-precision D/A conversion.
In addition, by adopting a double D/A converter system in which the left and right channels are independent, the time difference between left and right stereo signals is eliminated.
The digital filter uses an 8 x oversampling digital filter.
The drive unit of the pickup is equipped with a new double-floating mechanism using special viscoelastic low-resilience rubber and coil springs. In addition, the mechanical chassis made of materials with excellent shock resistance reduces the adverse effects of external vibration.
The front panel is made of extruded aluminum material for a luxurious feel.
