Denon DCD-1600NE, CD/SACD Disc player (various colors)

The integrity of musical signals is compromised when they are subjected to internal vibration caused by the rotation of the disc or the power transformer, or by airborne vibration caused by the sound being transmitted through the speakers. To counter this effect, Denon engineers have developed a vibration-damping design called Direct Mechanical Ground Construction. In this design, the power transformers, which are themselves the source of the vibration, are placed at the bottom of the DCD-1600NE, where unwanted vibration is directed directly to the ground and has no effect on the nearby circuitry. In addition, by placing the drive mechanism - the part with the most mass - low in the center of the chassis, the low center of gravity effectively suppresses internal vibration caused by the rotation of the disc, and also protects the mechanism from external vibration.

A philosophy of simplicity and clarity of design has been carefully implemented throughout the DCD-1600NE's circuitry. The circuit designs have been redesigned from the ground up to keep signal paths as short as possible and ensure that the original sound is accurately reproduced across the audio spectrum. As a result, interference between circuits and between left and right channels, as well as unwanted influences on audio signals, have been reduced to a minimum, reproducing precise, highly transparent sound. In addition, the power supply units for the digital and analog circuits, whose signals have different characteristics, have separate transformers to eliminate mutual interference and noise. The aluminum plate has also been bonded to the steel transformer base to enhance rigidity.
