The Evolution Line One is an accessible preamplifier from Trafomatic Audio, built with comprehensive five-plus-three input-output connectivity. The Evolution Line One brings Trafomatic's considered engineering to dedicated line-level signal control.

Key specs that matter

Five single-ended inputs and three single-ended outputs are provided. Gain is 22dBu. Input impedance is 47,000 ohms single-ended, with output impedance at 150 ohms. Frequency response spans 12Hz to 65,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 85dB unweighted, with total harmonic distortion plus noise at 0.3% - a characteristic figure for tube-based preamplification. At 450x320x105mm and 10kg, the Evolution Line One maintains a manageable, accessible tube preamplifier chassis.

Sound and use context

Expect the rich, harmonically resonant character tube-based preamplification is broadly celebrated for, with the characteristic 0.3% distortion figure contributing to the warm, engaging tonal signature tube enthusiasts seek.

Pairing

Trafomatic's own EOS and Evolution Elegance power amplifiers offer natural, brand-coherent pairings within the same broader catalogue.

Alternatives

Trafomatic's own Tara 30A offers a more comprehensive preamplifier alternative within the same broader catalogue.
