INTRODUCTION
Congratulations on purchasing the highly appraised "Black Shadow" amplifier
from "AUDION". Before we discuss circuit topology and design we would like to
introduce you to our company.
Audion was originally conceived by D.G.Chessell following his love of music, and
a long time hobbyist always delving into the depths of various components and
amplifiers. The concept in those early days was to allow people to get an insight
into audiophile high end without sacrificing their home or bank balance. This
overall picture still holds good for most of the current production, with just a few
bespoke built and designed products entering the upper echelons.
In 1986, David was given the position of Technical Director for "Audio
Innovations" at a time when the company had an enviable reputation for sound
quality. During this period and the next few preceding years a friendship
flourished between David, and the initiator of "Audio innovations", Mr. Erik
Andersson, one of Europe's top audio designers. Erik had recently returned to
live in his homeland of Sweden and was in the process of launching the
"EDISON Original" as a market leader in Scandinavia.
Audion was established in 1987 and caught the imagination of reviewers for their
top-flight performance and high build quality.
Following on from this, subsequent years saw Audion’s pre-amplifiers continue
to improve evolving into a two box state of the art design, with multiple on board
regulation quality hand built to military specifications. Our Quattro preamp was
also launched and set a standard becoming the ultimate in high-end audio pre-
amplification.
Erik in these years flooded the Scandinavian market with affordable Edison Kit's,
and a range of top-flight yet affordable triode amplifiers under the banner of
"Andersson".
In 1992 after a few depressed trading years in Europe and the saturation of the
Scandinavian market, two friends joined together with a base in the UK and were
able to design and distribute a superior amplifier around the world. Their first
joint product saw the "Black Shadow 845” mono-blocks, with a front-page debut
at the beginning of 1993 in the British press.
The Black Shadow’s provided, and still provide, affordable high-end true triode
amplifiers with no-feedback to be available to a large number of fortunate
audiophiles wanting outstanding sonic virtues.
