The Zero-One Family of CD Players launches a new era in digital sound reproduction.  Combining true DC coupling with an advanced analog filter ensures not only accurate frequency response, but also superior phase coherence.  This results in the music preserving its original dynamics, dimensionality and openness.  In addition, voices and instruments retain their proper timbre.  The high-frequency glare (bite), which has been a typical digital signature, is eliminated.  The mid-bass boom and low frequency muddiness which mars many high-end converters also disappears.   Furthermore, analog dithering helps to reproduce the smallest signals with uncanny accuracy. The use of a dedicated analog power supply together with the filter's superior stopband rejection (>120 dB) frees the analog signal of any digital noise and allows all of the music's nuances to be perceived.

The ability of the Zero-One players to preserve low level information combined with unprecedented phase and amplitude accuracy allow them to reach levels which until now were thought unattainable by the CD format. When compared to other CD players (regardless of price), the sound stage, resolution, detail, timbre, and frequency extension are unparalleled.  It combines many of the strengths thought to belong exclusively to the analog domain (low level resolution, sense of realism, and openness) with the known strengths of the digital format.

The Zero-One CD players are a complete package including CD transport, digital-to-analog converter (D/A), and high-resolution phase-coherent analog filter.  This eliminates the need for a separate transport, D/A, and the associated interconnect, while providing sound superior to separates at a fraction of their cost.  All of the CD players include a remote control. We offer a single CD player (pictured above) and a five-disk carousel-type changer (shown below). Both are available in either Epsilon or Omega grades.

Features:

• 4-pole linear-phase analog low-pass filter
• DC coupled analog section
• Regulated analog power supply with split-bobbin power  transformer
• Separate digital power supply (including transformer)
• Phillips 192x oversampling bitstream A/D Converter
• Phillips CDM 12 Transport
• Precision metal film resistors and polystyrene capacitors throughout analog section
• Gold-plated RCA jacks with Teflon dielectric
