reasons why Diva sounds great
DIVA designer T S Lim is a musician who will not compromise on
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.
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.
No unnecessary functions: no remote controls, no tone controls,
no balance controls, no mute switches, no delayed turn ons...
nothing to degrade sound quality.
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
All components are carefully tested and selected to ensure that
each component works in synergy with all the rest.
Diva products are extremely low in coloration. They are neutral
and so they mix and match well with other brands:
pre- and power amplifiers match well with other amplifiers; DIVA
power amplifiers work wonderfully with a wide range of loudspeakers.
The design focuses on the whole. Besides electronics, everything
else that affects sound quality is carefully considered:
dimensions, centre of gravity & material of the chassis; placement

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!
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.
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.
Preamplifiers use Wima & Ero capacitors in the signal path.
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.
~ Metal film resistors with 1 % tolerance within the signal path.
5% Carbon resistors with power rating greater than 2W.
OFC (oxygen free copper) cables. Although inexpensive, they are
the most musical sounding among over 100 cables tested.
Noble volume controls in active preamps, Tokyo Ko-Onn in the tube
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.
