The Mistral Intergrated is a simple to operate 50W/channel MOSFET amplifier, offering 5 inputs and a separate tape facility. A prime feature of the design is the point to point wiring and meticulous attention paid to printed circuit board layout. This has resulted in simple but clean signal paths, which improve both transparency and resolution. Also in an endeavour to raise the performance of the integrated amplifier above normal expectations, custom wiring and expensive high quality passive components are utilised. DC coupling is also employed to alleviate the degradation's caused by capacitors in the signal path. Further enhancements have been achieved by adopting an aluminium chassis and lid: thus reducing magnetically coupled distortions. Star earthing, separate power supplies for the input and output stages, together with a high current delivery, allow this amplifier to drive loudspeakers with ease.

The Mistral Phonostage is a self contained amplifier providing equalisation of the electrical output from Moving Magnet or high output Moving Coil cartridges. The gain is factory set for Moving Magnet, but can be configured for Moving Coil by simply soldering two links on the PCB. The performance has been enhanced by adopting a custom multiple hybrid active/passive power supply. The use of an over-rated mains transformer reduces power supply modulation effects, leading to a dynamic but smoother and less aggressive sound. Other features include custom wiring, Star earthing, dual mono construction and custom passive components. Although Operational amplifiers are employed in this design, special care is taken in their specification, such as: noise, gain bandwidth product and slew rate.

The Mistral Linestage is a dedicated line level preamplifier offering comprehensive input and tape recording selection. The low output impedance endows this amplifier with the abilty to drive relatively long or highly capacitive cables with ease. The linestage utilises a zero feedback cascode topology, very similar in concept to the LFD Linestage LSO. Another major consideration for this design was the power supply, which utilises a special semi-floating configuration. As a consequence the central Earthing point has its electrical potential actually defined by the signal earth, not the power supply. Ground modulation effects and other power supply defects are thus minimised by this approach. Dual mono construction, Star earthing and custom passive components all contribute to its transparency and high resolution. Please compare this model to higher priced competition, we are confident you will not be disappointed with its performance.

The Mistral Powerstage is a 50W/channel MOSFET power amplifier designed to drive the majority of loudspeakers presently available. The high input sensitivity allows the use of passive preamplifiers if so required. The circuit topology employed in this model is very similar in concept to the LFD Powerstage PA0. Essentially, the circuit consists of an input and driver stage running in Class A, feeding an enriched Class A/B POWER MOSFET output stage. As with other power amplifiers the power supply is very important. In this design, Ultra low impedance with fast recovery was realised by connecting multiple high quality capacitors in parallel. This approach produces far better results than using a single pair of commercial grade electrolytic capacitors of large value. DC coupling, Star Earthing, separate input/output power supplies and custom wiring also contribute to its outstanding clarity and resolution.

A 2 year research program has just been completed in order to select the optimum CD transport and D/A converter technology, in terms of performance and reliability. The result of this exhaustive research program is the Sony based Mistral CD player. An advanced Differential Converter (A.D.C) has been employed within the Mistral CD player for improved: noise performance, linearity and sound quality. Essentially, the D/A converter linearly interpolates the original sampling frequency, and then requantises the signal. A high order noise shaper removes the requantization noise before the signal is output via a pair of differential pulse-width modulated converters. To further improve sonic performance, separate isolated power supplies have been utilised for the digital and analogue sections of the CD player. Extensive regulation of the power supplies also contribute to the superb transparency and resolution of this player. Specially selected passive components and cabling have also been used to further enhance its performance.
