The
reasons why Diva sounds great
MUSICAL
DIVA designer T S Lim is a musician who will not compromise on
musicality.
For example, he chooses a Noble volume pot for the preamplifier
because it sounds the most musical, even though step-switch volume
pots give better clarity.
SIMPLE
This means having the shortest, most direct signal path. It also
means minimizing the use of active components. "If one tube
is enough, I would not add another," Lim explains.
MINIMALIST
No unnecessary functions: no remote controls, no tone controls,
no balance controls, no mute switches, no delayed turn ons...
nothing to degrade sound quality.
PURIST
Purity of the power supply has the greatest influence on sound.
In the mid- 1980s, Lim developed a special power circuitry, called
"ripple remover", to preserve the purity of the original
signal.
SYNERGISTIC
All components are carefully tested and selected to ensure that
each component works in synergy with all the rest.
NEUTRAL
Diva products are extremely low in coloration. They are neutral
and so they mix and match well with other brands:
Diva
pre- and power amplifiers match well with other amplifiers; DIVA
power amplifiers work wonderfully with a wide range of loudspeakers.
HOLISTIC
The design focuses on the whole. Besides electronics, everything
else that affects sound quality is carefully considered:
the
dimensions, centre of gravity & material of the chassis; placement
of components;
heat
dissipation...

You
will find some expensive, famous-brand components as well as some
inexpensive, lesser-known components. Expensive components are
not inserted to impress anybody; nor
are "cheap" components used to save costs. All are chosen
for one reason only: MUSICALITY!
TUBES
The best available NOS (new old stock) tubes are supplied with
Diva Pro Series & M-7 preamps, and Pro Series power amps.
EL34 power tubes from Svetlana, excellent sounding & inexpensive.
300B, 2A3 & 211 tubes from KR Enterprise or NOS.
TRANSFORMERS
Diva chooses different transformers to suit the needs of different
tubes and amplifier designs. Some are reputed brands from Europe
and Japan, others are from private transformer specialists in
China, Malaysia and Singapore. T S Lim also designs his own transformers.
CAPACITORS
Preamplifiers use Wima & Ero capacitors in the signal path.
Power
amplifiers are direct coupled between amplifier and the phase
inverting stage. They use polypropylene capacitors (obscure brand,
chosen for good sound) to couple the output tubes, and Ceraftne
clectrolytics as filter capacitors.
RESISTORS
~ Metal film resistors with 1 % tolerance within the signal path.
~
5% Carbon resistors with power rating greater than 2W.
INTERNAL
WIRING
OFC (oxygen free copper) cables. Although inexpensive, they are
the most musical sounding among over 100 cables tested.
VOLUME
CONTROLS
Noble volume controls in active preamps, Tokyo Ko-Onn in the tube
buffer
passive preamp. Many high-end preamplifiers use step-switch volume
controls which offer greater clarity and transparency, but the
Noble & Tokyo Ko-Onn controls sound more musical.
