Denon 110-Year Anniversary Series DCD-A110 SACD Player

The DCD-A110’s disc drive is equipped with the Advanced S.V.H. (Suppress Vibration Hybrid) Mechanism inherited from Denon’s high-end models. Signal paths have been shortened to an absolute minimum and circuits have been miniaturised to ensure that excess current and noise will not occur. The various parts are made with different materials such as a copper plate for the top panel to strengthen rigidity, diecast aluminium for the disc tray, and 2mm thick steel for the mechanism brackets.

Improvements in high-mass, vibration-resistant properties and the dispersal of resonation points contribute to a high level of vibration resistance. In addition, the mechanism’s low centre of gravity suppresses any vibration occurring inside the mechanism due to disc rotation, and the mechanism structure also effectively suppresses external vibration. By eliminating unwanted vibration, servo-related operations are minimised, and by also minimising unnecessary controls and current consumption, digital signals can be read from the disc with optimum accuracy under stable conditions.

Circuitry with Minimised Signal Paths

DCD-A110 circuits have been thoroughly designed to adhere closely to the “simple & straight” design philosophy. Circuit patterns have been reworked from the ground up to make the signal paths as short as possible and ensure that the original sound is faithfully reproduced across the sonic spectrum. As a result, interference between circuits and between left and right channels as well as adverse influences on audio signals are minimised, producing clean, highly transparent sound.

Direct Mechanical Ground Construction

The integrity of musical signals deteriorates when they are subject to internal vibration caused by disc rotation or the power transformer or to airborne vibration caused by sound pressure from the speakers. To guard against such influences, Denon engineers designed a vibration suppression structure called “Direct Mechanical Ground Construction”. In this design, the power transformers – themselves a source of vibration – have been placed close to the feet of the DCD-A110 where unwanted vibration is funnelled directly to the ground and prevented from affecting nearby circuitry.

Also, by placing the drive mechanism – the part with the greatest mass – low in the centre of the chassis, the low centre of gravity effectively absorbs internal vibration caused by disc rotation and also protects the mechanism from external vibration. To further shut out external vibration, the 1.2mm thick main chassis has been reinforced with two 1.6mm thick steel plates to produce a highly rigid three-layer structure with sufficient vibration-resistant mass.
