Pure Audio CD

The CD-2 is designed for audio only, and for this reason, using a pure audio drive is both simpler and better. All multi-format drives are based on video designs and clocks, and the audio output is then re-sampled (uncontrolled) to audio output clocks. Many choose to optimize the clock on the drive itself, but no matter what you do, ground potentials are difficult to control and the engine control board is noise-inducing.

The Lyngdorf Audio philosophy is to get the audio signal as clean as possible and to do the optimization based on the Lyngdorf Audio precision clock system. Based on previous work with CD players and fully digital amplifiers, we know the dos and don'ts of clock systems. The key is low phase noise in the audio band.

Electrical design

The Lyngdorf Audio designed switch mode power supply is extremely well regulated and is filtered and decoupled to provide a low noise and low impedance supply to the digital and analogue circuitry. With different supplies from four independent secondary windings on the transformer, the analogue and digital supplies are kept separate to minimize digital noise in the analogue circuit. Grounding is optimal, and the entire chassis is connected electrically. The back panel is electrically conductive.

Lyngdorf Audio spends great time and effort in designing products that will not radiate noise. Making a noise and radiation free design has the advantage that it will also make the CD-2 itself immune to noise from the outside and from products that have not had the same attention to details in the design phase.
