Preface of The Audiophile’s Project Sourcebook: 80 High-Performance Audio Electronics Projects by G. Randy Slone
The Audiophile’s Project Sourcebook is intended for electronics hobbyists and audiophiles who enjoy constructing their own “high-end” audio equipment, and who also desire a more complete understanding of the fundamentals involved with audio design. In addition, the information contained in this book will equip audio enthusiasts with the practical knowledge for experimentation and modifications to existing audio equipment, as well as clarifying issues of application compatibility. A well-rounded variety of domestic and professional audio projects is provided, including preamplifiers, filter circuits, headphone amplifiers, power amplifiers, effects circuits, power supplies, protection circuits, and display circuits. For the most part, these projects represent the state of the art in performance capabilities, and will exceed the performance parameters of most commercially available equipment.
In addition to the complete schematics and technical descriptions, I have provided the PC board artwork and layout illustrations for many of the more complex designs. I have assumed that the reader is experienced in the fundamentals of electronics and electronic construction, but I have made few assumptions regarding the reader’s expertise relating specifically to audio electronics. Appendix A provides a reasonably exhaustive clarification of audio electronics terms and modern “buzz” words as a further barrier against confusion. The Audiophile’s Project Sourcebook is for hobbyists and audiophiles who have been discouraged by the apparent schism between audio professionals and extravagant esoterics. It is designed to help anyone experience the ultimate in sonic quality at a reasonable expense.
The concepts and principles presented are not subjective, mythical, or traditional; they are scientific and extensively supported with provable analysis. Many readers will be pleasantly surprised at the low cost involved with even the best audio systems. Above all, I have directed this book toward people who want to experience the fun, satisfaction, and fulfillment of superb and practical electronic projects (not to mention the significant cost savings). This text is not infested with watered-down demonstration or educational projects—it is a sourcebook of impressive, high-performance designs that lend legitimacy to the reader’s construction efforts. I sincerely hope that many will enjoy it and benefit from it.
