Special Design Features

Mechanical strength has been a hallmark of Perreaux products since the company first started production back in 1974. The concept behind the physical design and construction is that each structural member should contribute to both rigidity and performance.

There is a separate regulated power supply for each section of the CD player. One positive supply and one negative supply for the sensitive analog output stage, another one for the DAC section, another for the clock generation of the DAC section and a further supply for the microcontroller and display. The advantage of this is that there is complete isolation from stage to stage, ensuring the analog section is completely free from digital noise.

The CD1’s precision transport is backed up by a Burr Brown (Texas Instruments) digital to analog converter. Multi-level Delta-Sigma operation with 8x over-sampling ensures the CD1 will deliver a high level of audio performance.

The CD1 offers a balanced analog output, providing improved noise rejection and cancellation.
