There
are very few modern designers in the audio field who
can claim as much as Tim de Paravicini. No aspect of
the recording and reproduction chain has been left untouched,
no aspect of circuit design not further researched and
developed.
As early as 1965
Tim was involved in custom design work for rock and
roll bands; manufacturing his own public address equipment,
and modifying existing studio equipment to realise even
greater potential.
A
move to South Africa from England saw a further development
of his own unique design genius, and the launch of his
own professional amplifier product, sold simply as “de
Paravicini”.
While working in
South Africa, Tim had a chance meeting with representatives
of the Lux Corporation, and in 1972 was invited back
to Osaka, Japan, and offered a job as audio designer.
Tim soon put together some very interesting designs
for Lux, including the remarkable C1000/M6000 pre/power
amplifier combination.
One of his own favourite
designs from this period was the Luxman 3045 tube mono
block. At the time, this was the only mono block design
available in the audio field, and backed up de Paravicini’s
preference for locating the power amplifiers close to
the loudspeakers. Tim also designed the actual output
tube for this amplifier, the 8045 power tube. As always
with his designs, the output transformer was a custom
de Paravicini design.
In 1976 de Paravicini
returned to England, and very quickly made an impact
as a design consultant, initially working with the ALBA
Radio Corporation, and Tangent Loudspeakers. Tim was
also responsible for the later ranges of Michealson
and Austin tube amplifiers, including the TVA10 and
M200 mono blocks. Within a year, he had set up Esoteric
Audio Research Ltd., and was marketing the remarkable
EAR 509 100 watt professional tube mono block power
amplifiers. He developed a unique output transformer/tube
interface circuit called “balanced bridge mode”, in
which all the electrodes (except the control grids)
have their own separate windings on the thirteen-section,
biflar wound, output transformer. In addition, the amplifier
has no overall feedback, something of a de Paravicini
trade mark. Technically this amplifier proved that tubes
are capable of performing equally as well as transistors
in a laboratory, with a specification that included
a power bandwidth of 9-85,000 Hz, -3dB, and also proved
that tubes are capable of better things than the “retro”
sound some manufacturers look for.
Subjectively
the 509 amplifiers were a big hit. Although aimed at
the professional market, several Hi-Fi magazines picked
up on the 509’s, and compared them to the then State
of the Art domestic High End equipment. The fact the
509 beat all of the competition at the time helps explain
why the 509 is still in production today.
The 509 was designed
by de Paravicini to have no sound; trying to sum up
the 509 is hard, it does not offer the warm ‘comfortable’
tonal quality which so often mark most tube amplifiers
out. They are remarkably clear, transparent, with firm
realistic bass, effortless top end, detailed and very
alive.
In the twenty years
since 1976, Tim has designed a mammoth catalogue of
Hi-Fi and Studio components, both for Esoteric Audio
Research and for other domestic audio companies. Currently
the ‘E.A.R. professional product range includes
a tube capacitor microphone, built with a rectangular
gold spluttered capsule. A design which easily betters
the classic European designs.
Tube
microphone preamplifiers, tube equalisers, record cutting
systems, analogue to digital converters (for CD mastering)
plus custom components and servicing for some of the
Worlds most famous recording artists. His is most famous
in the studio industry for the stunning analogue tube
master tape recorders. These units have very special
custom designed heads, and are capable of digital levels
of signal to noise ratio, with a bandwidth in excess
of 8Hz to 80,000Hz!
Work for the recording
industry has brought critical acclaim. On the ‘Waterlily’
label, “A Meeting by the River” received a prestigious
‘Grammy’ award for its sound quality. This was a mid/side
technique recording using a pair of crossed microphones.
Waterlily’s microphones, preamplifiers, analogue master
recorder and A/D converter were all built and designed
by Tim.
In 1985, de Paravicini
introduced his new record cutting system. Now installed
at ‘The Exchange’ in the heart of London, (originally
Island Records ‘Sound Clinic’ facility). This is phase
corrected, and uses in excess of 1,000 watts of tube
audio power, based on the classic EAR 509 circuit. The
cutter head is again, a custom design, and is capable
of cutting deeper, wider grooves than any other system.
The result is higher dynamics, with a true signal to
noise ratio in excess of 65 dB from records pressed
off a master cut on this system. It is truly as close
to the original master tape as it is physically possible
to get.
Throughout
the past twenty years, Tim has worked with many different
manufacturers. For London based Musical Fidelity, Tim
designed the amazing A1, taking the concept of a cut
down ‘High End’ audiophile amplifier, the only compromise
being the 10 watts output, albeit pure class ‘A’. Other
products designed for ‘M.F.’ include the A470/370, P270,
Digilog, CD-T, etc.
More recently in
Europe, the ‘Tube Scene’ in domestic audio has really
taken off. A lot of European manufacturers have stolen
both older European designs, and designs from Japanese
magazines and journals. Most of these amplifiers are
very poor sounding, and terribly unreliable. These manufacturers
neither understand the designs or how to build them.
They use the reputation of tubes to sell their poor,
none original product. De Paravicini’s answer to these
companies, was the award winning EAR 859 amplifier.
His all new Enhanced Triode Mode circuit bettering the
performance of directly heated triodes designs. It provided
the public with a real design, from a professional maker.
The
EAR 834P phono stage was also introduced, and similar
to the ‘859 has proved very popular, offering un-rivalled
performance per dollar. The particular speciality being
the stunning Moving Coil stage transformers - transformer
design being one of Tim de Paravicini’s fortes - unlike
most manufacturers, who just buy in ‘off-the-peg’ transformer
designs or just specify the most basic requirement to
an outside supplier.
All EAR amplifiers
are truly original, including the custom transformer,
metal work, circuit printed cicuit board. All the work
of Tim de Paravicini.
Tim works by a simple
premises: If he designs it, it must be a better design
than anything else, or he will not manufacture it. His
sole goal is taking audio to the furthest possible point
of development. Current research is taking him further
along this path than any single competitor.
A review by What
Hi-Fi in November 1998 under the group title of
"Ultimate Amplifiers" seems to sum up the
de Paravicini magic:
The Yoshino
V20 was given five stars and the following comment
rounded off the article:
'What
E.A.R have done is to create an amp with such style
and build quality that it makes most other kit seem
as aesthetically pleasing as a baked bean tin. That
such style is combined with top quality sonics is
cause for celebration.'
