PRIMALUNA EVO 100 INTEGRATED

Tube Integrated Amplifier

The PrimaLuna EVO 100 Integrated is a tube integrated amplifier designed to deliver an authentic and immersive listening experience, blending artisanal craftsmanship with the most advanced tube technology. From the very first glance, it impresses with its attention to detail and solid construction: every component is carefully selected with the goal of maximizing sonic performance and product longevity.

Unlike many tube integrated amps on the market that use solid-state circuitry for headphone output, the EVO 100 utilizes the same tube section dedicated to the loudspeakers, delivering an exceptionally rich, detailed, and natural headphone listening experience. There is no need for a separate headphone amplifier: the EVO 100 is engineered to satisfy even the most demanding headphone enthusiasts, whether they use Sennheiser, Hifiman, or Audeze.

A key innovation in PrimaLuna products is the Adaptive AutoBias system. This is a true smart circuit, completely passive and outside of the signal path, that automatically adjusts tube operation in real time, reducing distortion and extending tube life. In the event of a tube failure, the amplifier enters protection mode and indicates the tube that needs replacing via a red LED. No technical complications, no risk to internal components—just swap the tube and get back to listening.

The power supply section features a massive custom toroidal transformer, resin-potted for vibration damping and shielded to minimize acoustic noise and electromagnetic interference. The output transformers are also custom-designed and wound in-house by PrimaLuna—essential components that ensure wide and controlled frequency response, from deep bass to airy highs.

All circuitry is built using point-to-point wiring, a technique that prioritizes ultimate quality and relies on skilled hands to make every internal connection. No printed circuit boards are used in the signal path—only hand-soldered heavy-gauge conductors.

The EVO 100 was deliberately designed without an internal DAC or phono stage—a conscious choice to prevent premature obsolescence and give users the freedom to pair the amp with external sources tailored to their needs and preferences.

Lastly, the EVO 100 is engineered to run its tubes gently and carefully: lower operating voltages mean greater reliability, reduced risk of failure, and significantly longer tube life. With well-managed power and natural dynamics, this amplifier delivers a full-bodied, musical, and incredibly expressive sound—one that naturally enhances every music genre with depth and authenticity.
