About the Preface

The Chapter Audio Preface is a high-performance stereo preamplifier designed with meticulous attention to audio quality. It uses the best sounding Burr Brown OPAMPS and ultra low ESR electrolytic capacitors from Samwha or Panasonic Gold series. The power supply includes custom screened mains transformers and high-quality regulators. The preamplifier features full immersion gold printed circuit boards and precision MELF surface mount resistors, enhancing sonic clarity and dynamics. It offers wide bandwidth to preserve high-frequency phase information essential for stereo sound staging and realism, with a high-speed differential input stage and carefully designed frequency compensation. The balanced ground layout reduces inter-modulation distortion and crosstalk. Inputs include two pairs of true balanced XLR inputs and five single-ended RCA inputs, with balanced and unbalanced preamp outputs for bi-amping. The mains input includes a filtered IEC inlet with a 10A T type fuse for clean power delivery. The unit is known for a warm yet detailed sound character with excellent holography and dynamics. It is built solidly with high-quality components and craftsmanship, making it a respected choice among audiophiles.
