Welcome
TAURUS PRE is a fully balanced line stage pre-amplifier. It is the finest coalescence of art
and passion by inheriting the design essence of analog recording equipments from the
‘golden age’ and aesthetic taste of this new era.
Together with MERAK, the power am-
plifier, TAURUS PRE would bring an ideal audio playback system, which is fantastic
enough to please the most enthusiastic audiophile.

AURALiC ORFEO Class-A Output Module
Inspired by Neve 8078 analog console’s circuit design, AURALiC developed ORFEO
Class-A module. The principle of this module is to use a mass of small signal com-
ponents with best linear characteristic. By packing them though a thermal balance
procedure and bias the transistors into Class-A, ORFEO achieves impressive per-
formance with open loop distortion less than 0.001%. With such sophisticated design,
ORFEO shares the same warm and natural sound with Neve 8078. The ORFEO
module used in TAURUS PRE was tweaked with optimized bias current so it will be
better fit for pre-amplifier use.

Low Noise Input Buffer
The low noise input buffer in TAURUS PRE is specifically designed by AURALiC to
meet the requirement for pre- amplifier usage. It presents great linearity with a
maximum undistorted input level as high as +24dBu, making it almost impossible to
overdrive and well suite for any source component. This buffer also owns an excla-
matory low noise of less than 1uV while maintains high input impedance (100K of
RCA and 200K of XLR). With this circuit design, TAURUS PRE has a dynamic range
over 130dB and possible to fit into any kind of source, even with high output imped-
ance devices such as valve buffered CD, it can still easily capture every details and
ensure the reality of music impression.

Advanced Purer-Power™ Solution
To satisfy TAURUS PRE’s extremely low noise design, AURALiC introduce the ad-
vanced Purer-Power solution. The new solution utilizes our triple shielded main
transformer customized by Plitron. Comparing to the usual shield transformer, triple
shield transformer has much lower EMI; the noise level raised by a triple shield
transformer is even below measurement's resolution. Purer-Power solution can
strongly isolate common-mode and differential-mode interference from both within
and outside audio band as high as 90dB while reshape the electrical circuit and re-
move DC current. It can also effectively prevent electrical circuit from being interfered
by those current entering into system via power supply, by which means to ensure
more stability of circuit and more purification of sound.
