Pre-Amplifiers
Since the original M3 pre-amplifier was introduced in 1996, the M3 and its derivatives have enjoyed considerable success. They have consistently won the "Pre-Amplifier of the Year" award from Hi-Fi Review in Hong Kong, starting in 2001 and almost every year since.
The M1 starts the performance envelope where most other pre-amplifiers cease.

Materials and component quality M1 Line
All our pre-amps are available as 'Phono' version designed as a proper record collector’s control centre and feature a stereo – mono switch and the most direct and cleanest signal path possible, with no tape input or loop. They are really designed to maximise the quality of all LPs made with the RIAA curve, whether mono or stereo.
Materials and component quality M1 RIAA
The M1 - M8 preamplifiers come as a 'RIAA' only version for those who use integrated amplifiers or have a line only pre-amp. The performance of our RIAA Preamps is already legendary. Being major record collectors, we have always felt the need for a top flight phono-stages, focussed on getting the absolutely best from the LP, whether mono or stereo.

M2
It is well known that the accurate reproduction of music, not just sound, requires the purity of the incoming signal to be preserved. It is therefore not difficult to conclude that, in order to achieve this goal and to retain the musicality of the original performance, the complexity of the circuitry itself must be kept to a minimum. In response to this, the M2 Pre Amplifier uses a single-ended, zero feedback circuit topology. This is simply the most linear design possible, demanding pure Class A valve operation and removing the need for a phase splitter, which introduces unnecessary crossover distortion.
In contrast to the majority of the audio industry, we design our circuits with the aim of minimising non-harmonic and time base anomalies, rather than producing vanishingly small harmonic or low intermodulation distortion measurements. These non-harmonic amplitude and time base distortions have a highly perceptible and adverse affect on the signal waveform, and it is far more important to address these factors than participate in the increasingly irrelevant numbers game that chases „perfect measured response‟.
As a result, the M2 was designed for maximum linearity and minimum transient distortion, and avoids the need for detrimental „corrective‟ measures, such as inherently error-prone feedback loops.
