Overview
PrimaLuna EVO 100 Tube Preamplifier
Dual-mono architecture. Tube-rectified power supply. Precision analog volume control.
The PrimaLuna EVO 100 brings sophisticated vacuum tube engineering to a compact, dedicated stereo preamplifier. Its dual-mono design features separate toroidal power transformers, six vacuum tubes, and hand-wired point-to-point circuitry.
PrimaLuna's SmartGain circuit provides 10.8dB of gain to help minimize unwanted noise, while the PerfectMatch input circuit is designed to maintain consistent loading for connected source components. Four stereo RCA inputs, an ALPS Blue Velvet volume control, and remote operation complete a straightforward analog design.

A Dedicated Analog Preamplifier
The EVO 100 does not include a built-in DAC or phono stage, allowing you to choose separate components for digital playback and vinyl. Unlike the EVO 200, EVO 300, and EVO 400 preamplifiers, it does not feature Home Theater Bypass.
Pair it with the PrimaLuna EVO 100 power amplifier or another compatible power amplifier for a complete two-channel system.
