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

The integrity of musical signals is weakened when they are subjected to internal vibrations caused by disk rotation or power transformers, or vibrations caused by air due to sound transmission in speakers. To protect against such influences, Denon engineers have developed a vibration dampening structure called Direct Mechanical Ground Construction. In this design, the power transformers, which are themselves a source of vibration, have been placed at the bottom of the DCD-1600NE, where unwanted vibration is routed directly to the ground and has no effect on nearby chips. Also, by placing the drive mechanism - the part with the most mass - low in the center of the chassis, the low center of gravity effectively stops internal vibration caused by disc rotation, and also protects the mechanism from external vibration.

The simple and clear design philosophy has been carefully implemented in all DCD-1600NE circuits. Circuit designs have been redesigned from the ground up to make signal paths as short as possible and ensure that the original sound is accurately reproduced across the sonic spectrum. As a result, interference between circuits and between left and right channels, as well as unwanted effects on audio signals, have been reduced to a minimum, reproducing accurate, highly transparent sound. In addition, power supply units for digital and analog circuits, whose signals have different characteristics, have separate transformers to eliminate mutual interference and noise. An aluminum plate was also bonded to the steel transformer base to increase rigidity.
