1 Introduction
Thank you for purchasing one of our amplifiers, a
lot of care has gone into the design, selection of
components and production of this amplifier. We
are sure that you will hear the difference.
The Stereo 20 is an integrated stereo amplifier
using the excellent EL84 pentodes in class A/B
giving the first few important watts in ‘Class A’
then sliding into ‘Class B’ at higher powers. The
first stage is a 12AX7 double triode (one ½ per
channel) driving a 12AU7 phase splitter. We have
used top quality audiophile components
throughout. The simple design means the Stereo
20 is capable of a smooth detailed illumination of
you recordings without harshness or listening
fatigue.
Despite its moderate price and compact size,
with the suitable source material and
loudspeakers the Stereo 20 is capable of
stunning performance!
We cannot emphasize enough about the
importance of using efficient quality speakers.
Icon Audio would like you to get the best out of
our amplifier. Please read the enclosed notes. We
have tried to give you all the basic information you
will need, even if you are not experienced with hi
fi.
We would recommend that everyone follows
the ‘quick set up guide’.
Should you be
uncertain about anything to do with your STEREO
20 please contact your dealer or ourselves.
Hi fi reproduction is a long chain of events
processes that starts with the acoustics and
mixing in the recording studio, before being
transferred to a medium such as LP, CD, or FM,
ending with the playing through your own player,
amplifier and finally loudspeakers.
Your room acoustics will also affect the sound
before it finally reaches your ear! Whilst the
amplifier is arguably the most important part of a
system, it is important to remember the ‘weakest
link’ will always affect the final results when
making judgements.
An amplifier which faithfully reproduces the input
signal will of course also reproduce imperfections
in the tonal balance and the recording itself.
