Description :
The Audio Note M2 Line is a full function tube preamplifier represents an uncompromising solution to the problem of low-cost, high-performance music playback systems. It is well known to any audio circuit designer that accurate reproduction of music relies entirely on the preservation of the purity of the incoming signal. It is therefore not a difficult step to make to realize that the complexity of the circuitry itself must be kept to a minimum in order to retain the musicality of the original performance. In response to this, all Audio Note M2 Line use a single-ended, zero feedback circuit topology. The single-ended gain stage topology is simply the most linear, demanding pure Class A valve operation and removing the need for a phase splitter, which introduces unnecessary crossover distortion.
The Audio Note M2 Line does not make use of any kind of feedback. As a result, it is neither designed for vanishingly small harmonic or low intermodulation distortions, but instead for minimal non-harmonic and time base anomalies. These non-harmonic amplitude and time base distortion that have a highly perceptible and adverse affect on the signal waveform. The Audio Note M2 Line is designed for maximum linearity without ‘corrective’ measures to keep transient distortions to a minimum rather than introducing the recursive errors inherent in feedback loops. Components incorporated in the line stage are paper-in-oil capacitors, Audio Note pure silver wiring for signal output and Black Gate electrolytic capacitors in critical parts of the power supply
