PROLOGUE
A COMPLETELY FRESH
LOOK AT
HIGH FIDELITY SOUND REPRODUCTION
Music and sound
reproduction
Music is an expression of the soul of
the composer, and the feelings and
emotions of the musicians who have to
interpret and express their reading of
the composer’s conceptions.
Technical skills assist in conveying the
music, capturing it in a reusable format
and then reproducing it.
The goal in using technical skills is
communication of the music in such a way
that the listener can completely and
wholeheartedly empathise and be at-one
with the music. This can be at several
levels, but for sound reproduction at
the highest level of fidelity it should
communicate as though it were being
heard “live”, with the listener present
on the occasion.
Energy, sound
reproduction and electronic fields
Energy is everything. Nothing is really
“solid”. “We” are energy, the sound we
hear is energy and the “equipment” used
to produce or reproduce it is energy.
Energy manifests itself as vibration.
Therefore, by extension, everything is
vibration in some form or another.
Anything that vibrates has a waveform,
which extends out into a wider world.
Accordingly, all references to “energy”
should also embrace the “vibrations” and
“waveforms” that emanate from that
energy.
The vibrations operate at different
speeds and, in the case of material
things, have different atomic
(electrical) properties and densities.
The foregoing combine to create
electronic fields of various kinds. The
very proximity of material things
creates further vibrations, as the
surrounding electronic fields “clash”.
Present-day instruments can measure some
of the electronic fields that exist
around our equipment, but many such
fields are of a kind that cannot yet be
measured. This may change in the future
as mankind’s knowledge increases.
Instruments cannot measure the feelings
and emotions contained in sound, but
such aspects to the sound can be
assimilated and interpreted by human
beings. Much depends upon the clarity of
the sound in the form of the vibrations
that are received. However, this
“clarity” is muddied by the numerous
“clashes” of electronic fields and other
vibrations that are all part of
mankind’s attempt at sound capture and
reproduction.
Relativity of sound
reproduction
A little over a hundred years ago,
everyone marvelled at the early attempts
at sound reproduction. Today, sound
quality is several leagues ahead of what
was initially achieved. Each time
technology genuinely advances, we are
amazed and delighted with the
improvements we can perceive. But at
each stage the improvement is relative,
because unless we have the opportunity
to hear a further improvement in sound
quality, we are naturally content, as
were our forebears, with the best that
appeared to be available at the time.
Availability is a varied thing. What is
available to one person is not to
another. On the one hand, it may be a
question of the means to afford certain
equipment, on the other, a simple matter
of lack of opportunity to experience it,
except, if we are lucky, through a good
demonstration.
Clarity v musicality
Whilst we are delighted to be able to
hear more of the aspects of each sound
as technology improves, this does not
necessarily mean we hear more of the
music. Unless the feelings, emotions and
conceptual ideas of the composer, as
interpreted and expressed by the
musicians, are completely communicated,
as in the case of a ‘live’ performance
being heard ‘in person’, clarity of
reproduced sound is only part of the
true experience.
Relativity of
musicality
Musicality is also relative, and is not
dependent on absolute clarity of sound.
In the early days of sound reproduction,
the musicality of the sound could, by
the values of the day, be judged as very
high.
It is mainly a question of timing and
dynamics and of bringing out those
aspects of the sound, such as
intonation, inflections and timbre of
the voice/instrument, etc., which
distinguish the character of the sound
of one artist from that of another. The
ambience of the recording venue is also
an important aspect in the recreation of
the original performance.
All the foregoing provide a sense of the
occasion, all the feelings and emotion,
which have to be conveyed if the
musicality of the reproduction is to be
fully realised.
Achieving fidelity to
the original performance
Energy is everything, in both the
recording and reproduction processes. In
order to achieve fidelity to the
original performance, it is essential
that these processes be carried out in a
situation of harmony amongst all the
energies involved. Too often, the design
of products and the use of materials
inhibit this harmony.
Nevertheless, the fundamental ideas
behind the techniques used do enable a
reasonable signal to be derived,
sufficient to demonstrate that, with
care, it should be possible in the
future to make considerable strides in
improving the quality of sound
reproduction.
Harmony of the energies is an essential
starting point, and this is where the
importance of all the products of
Ringmat Developments comes into play.
They all embody aspects of harmony of
the energies, with particular emphasis
on the geometry of resonance (vibration)
in materials and the unique way in which
the products of Ringmat Developments
dissipate or harmonise unwanted energy.
Another feature is the use of particular
types of materials and their orientation
that help the harmony of the energies.
This means that fancy, expensive looking
materials cannot be used, because of the
electronic fields associated with such
materials, and often their colours.
Yet another feature of the products of
Ringmat Developments, and perhaps their
most important, is the way their
harmonies overlay others, thus
dissipating, to some extent, the lack of
harmony in the energies of those other
products. In this way, damage to a
signal from a lack of harmony in the
energies of certain products is
minimised when used with those designed
by QR Design for Ringmat Developments.
Because of their influence on the sound,
the products of Ringmat Developments are
absolutely central to sound reproduction
(and also to the recording processes),
and are neither peripheral nor
“accessories” to the principal equipment
used.
Breaking down barriers
Many people believe that, having bought
their hi-fi equipment, nothing further
is needed in order to achieve sound from
the equipment. Sadly, the absence, at
most audio retailers around the world,
of comparative reproduction processes
that encompass the ideas expounded in
this article and elsewhere in our
literature, and on our Website (www.ringmat.com),
severely limits the horizons of the
buyer with regard to his or her
expectations. All too often, comparative
reproduction processes are no better
than “more of the same”.
Buying the principal equipment is only
part of the process of establishing a
sound reproduction system. This is not
to denigrate the value of the equipment
already in use, or to be purchased, only
to explain that their use is limited
without harmonising the energies
involved in their use. At present, only
the products of Ringmat Developments and
a few others effectively achieve this.
The above conceptions need to be spread
and shared, and through editorial
coverage and reviews in hi-fi magazines,
Internet forums and other forms of
media. Also by word of mouth from user
to user, but this is a long, slow
process, which is why this article has
been prepared; to help, not only members
of the public, but also those in the
relevant industries that have to
initiate a number of changes and to set
new standards.

Appendix A
History of Stereo
Recording and Reproduction
Even from the earliest times of
electronic sound reproduction, there has
been a dream of achieving greater
realism in the sound reproduced, such as
one hears when being present at a “live”
performance. Even before my teens, I
spent hours with our two mono
radiograms, first an Ultra, with a heavy
1930’s 78 rpm tonearm, then a Ferguson,
with a lightweight 33⅓/45/78 rpm auto
changer, trying various ideas in order
to create realistic spatial effects
using extension speakers. This was well
before stereo was introduced but a long
time after M. Clément Ader gave a
directional sound demonstration at the
Paris Exposition of 1881.
M. Ader set up some early carbon-rod
microphones to the left and to the right
of the stage at the Paris Opéra and
connected them by separate telephone
wires to banks of earpieces at the
Exhibition Pavilion. By holding a left
and right earpiece to the appropriate
ear, visitors were amazed with the
spatial sound reproduction they received
and found that they could follow the
movements of the sound sources,
principally the singers, as they moved
about the stage. Further experiments
followed, but it was not until 1931
that, in British Patent Number 394,325,
Alan Dower Blumlein (1903-42) described
his all-embracing theories and practical
designs for recording and reproducing
two-channel sound via a disc medium.
Mr. Blumlein suggested a number of
microphone arrangements, the most famous
being a pair of bi-directional
microphones at right angles to each
other and placed as nearly together as
possible to eliminate time-of arrival
differences at the two microphone
diaphragms (the ‘Blumlein method’). From
these two microphones, wires would carry
the sound to a disc medium where they
would be inscribed as two mutually
independent channels of information in a
single record groove, one groove wall
for the left channel and the other for
the right channel. The grooves would be
inscribed at right angles to each other
and at +/- 45° to the record surface. In
1957, worldwide agreement was reached on
the method by which a stylus would trace
the “stereo” groove wall modulations and
convey the separate left and right
channel signals to the amplification
system. From the amplification system,
the respective left and right signals
would be conveyed to two loudspeakers in
front of the listener, suitably spaced
out to the left and right. By reason of
the differences of intensity that sound
sources reached each of the two
microphones, it was possible, as the two
microphones respectively received these
sounds, to correspondingly place each
sound source within the soundstage
created through the loudspeakers. Stereo
records using the above method were
launched in 1958, but it was possible to
obtain two-track open-reel tapes
similarly inscribed from 1955.
“Musicassetes” in the Philips Compact
Cassette format followed, then digital
recording techniques, Compact Discs and
other forms of digital reproduction. But
they all followed Mr. Blumlein’s
original concept for capturing and
inscribing independent left and right
channels where the modulations so
inscribed are traced to the left and to
the right by a single stylus, or other
tracing mechanisms in the case of the
later developments.
