It is well known that the accurate reproduction of music\u2014going beyond mere sound\u2014requires preserving the purity of the input signal. Consequently, it follows that to achieve this goal and retain the musicality of the original performance, the complexity of the circuitry itself must be kept to a minimum. To this end, the M2 preamplifier employs a single-ended, zero-feedback circuit topology. This design offers superior linearity, relies on pure Class A tube operation, and eliminates the need for phase splitters, which would otherwise introduce unwanted crossover distortion.<\/p>\n
Unlike much of the audio industry, our circuit designs aim to minimize non-harmonic and time-domain anomalies rather than simply achieving vanishingly low harmonic or intermodulation distortion figures. These non-harmonic amplitude and time-domain distortions have a highly audible, detrimental effect on the signal waveform; addressing them is far more important than engaging in the increasingly irrelevant numbers game of chasing “perfect” measured response.<\/p>\n
Therefore, M2 is designed for maximum linearity and minimal transient distortion, avoiding the need for detrimental “corrective” measures such as inherently error-prone feedback loops.<\/p>\n
