Based upon the design concept of Neve analog console, combined with modern aesthetic of music, AURALiC invent the OREFEO Class A output module and fit it into TAURUS PRE. Thanks to the brand new designed low noise input circuit and better power solution, TAURUS PRE achieves a remarkable residual noise performance at 3uV in minimum, this allows it to handle micro dynamics in the music by a perfect way with a liquid transparency
To make it easier to enjoy the pleasure of music, TAURUS PRE is equipped with remote control and various I/O ports. Three sets single-ended and one set balanced input ports allow you switch back and forth between different music sources. While the single-ended and balanced output ports can deliver musical signals simultaneously, driving different back end. Furthermore, with high quality headphone ports, TAURUS PRE can shut the noisy world out and enable you to immerse yourself in the pure and magnificent world of music.
AURALiC OREFEO Class-A 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 components with best linear characteristic. By packing them though a thermal balance procedure and bias the transistors into Class-A, ORFEO achieves impressive performance 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 optimised 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 exclamatory 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 impedance devices such as valve buffered CD, it can still easily capture every details and ensure the reality of music impression.
Advanced Purer-PowerTM Solution
To satisfy TAURUS PRE's extremely low noise design, AURALiC introduce the advanced Purer-Power solution. The new solution utilises our triple shielded main transformer customised 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 remove 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.
