CDA 825 demo

As a result of our quest to refine the musical capabilities of the CD-medium and our constant efforts to understand and target the underlying technological requirements, we believe that the introduction of the CDA825 offers significant improvements of sound reproduction from CD-media.

Obviously, the CD-medium is a digital representation of an initially analog event, and the design of the CDA825 is therefore determined by an ambition to reconstruct the complex and delicate harmonic structure of the original analog waveform. This objective adheres to all details of the design, as well as their integration into the whole. Starting with the power supply, the following paragraphs offer some insight into the various design considerations.
Power Supplies

The routing and grounding scheme of the CDA825 power supply provides effective isolation between the digital and analog parts of the CD-player. Furthermore, the power supply has been designed to ensure constant low output impedance towards the power consuming electric circuits. The numerous individual power supplies in CDA825 are designed to operate with a constant power, thereby eliminating reverse modulation towards the transformers and the AC supply grid.
