TWILIGHT AUDIO
When the deep purple falls . . . and the stars begin to twinkle in the sky . . .
TWILIGHT AUDIO is the Trade Designation chosen for Tube Audio Equipment designed and manufactured by KARL M WIESSMANN - ELECTRONICS CONSULTANT, at our Laboratory on Harrison Street in Sussex Borough, New Jersey, USA. Each and every piece of equipment is meticulously hand crafted by the Twilight Audio Team, consisting of Karl, his Laboratory Assistant, Deb Gonnoud, and our Laboratory Technician, Diane Keary.
The entire purpose of TWILIGHT AUDIO is to provide an outlet for proprietary designs of unique and uncompromising quality, resulting from Karl's half century of experience with Tube electronics. Not just another pretty face, the equipment is not "fancy". It's inherent beauty lies in the design quality and functionality that will ultimately redefine high-end audio.
Production lots are necessarily small, typically consisting of 10 or less units (or pairs); and there is a waiting list.

COMMON FEATURES OF TWILIGHT AUDIO EQUIPMENT:
Proprietary solid state, passive, nearly unity power factor HV rectification scheme.
Proprietary solid state, passive, nearly unity power factor Filament rectification scheme.
Time Delay before HV application to allow filaments to fully heat, prolonging tube life.
Zero Crossing switching of AC line to eliminate surges and transients, burps, blurps, murmurs, and blips.
Separate HV supplies for individual amplification stages, eliminating unwanted interstage coupling, and enhancing power utilization efficiency.
Unique, proprietary capacitor utilization scheme in power supplies and signal path, eliminating or minimizing capacitor "coloring".
