EVO 300 Tube Integrated Amplifier

PrimaLuna: Where Craftsmanship Meets Sonic Excellence

PrimaLuna products are built to delight the senses — even before they’re powered on. From the outside in, every detail reflects an unwavering commitment to quality, longevity, and sonic purity.

Handcrafted with Purpose

Every PrimaLuna component features handmade construction with a heavy-gauge, fully vented steel chassis, finished in a luxurious five-coat process — each layer hand-rubbed and polished to perfection. Inside, true point-to-point wiring is executed using the finest Swiss silver wires, a level of detail typically reserved for only the most exclusive tube amplifiers.

Elegant Control, Built to Last

Forget flimsy plastic remotes — PrimaLuna provides a heavy metal remote control that’s both ergonomic and elegant, matching the substance of the product itself.

Speaking of weight, you’ll feel the difference the moment you lift a PrimaLuna. Every model houses custom-designed toroidal and EI-frame transformers, built to the precise specifications of a renowned U.S.-based transformer expert. These fully encapsulated transformers ensure low noise, superior isolation, and deliver massive bandwidth and powerful speaker control — making PrimaLuna famous for combining lush tube warmth with crystal-clear highs and solid, authoritative bass.

Premium Components Throughout

• Motorized ALPS volume control

• Nichicon & DuRoch polypropylene/tinfoil capacitors

• Super-fast Philips rectifier diodes

• Ceramic tube sockets for durability and heat resistance

• Gold-plated, panel-mounted RCA inputs

• WBT-style speaker terminals (solid shaft for optimal conductance and reliability)

True Tube Headphone Amplification

Each EVO integrated amplifier doubles as a true vacuum-tube headphone amplifier. There are no op-amps or chip amps here — your headphones are driven by the same all-tube signal path as your speakers.

100% Shielded Phonostage Option

EVO models feature a shielded, chassis-mounted phonostage compartment, allowing easy installation of PrimaLuna’s optional PhonoLogue moving magnet circuit. This design isolates the phonostage from other circuits for maximum sonic purity.

Advanced Protection and Smart Features

• SoftStart™ Circuit – Increases the life of sensitive components, while minimizing tube stress on startup.

• Adaptive AutoBias™ – An exclusive PrimaLuna technology that actively monitors and adjusts tube bias in real-time without entering the signal path. Reduces distortion, improves performance, and removes the hassle of manual adjustments.

• High/Low Bias Switch – Makes tube rolling easy. Switch from EL34 to KT88 tubes without meters or screwdrivers.

• Enhanced Output-Stage Protection – A smart relay protects transformers, resistors, and power supplies from damage in case of catastrophic tube failure.

• PTP™ (Power Transformer Protection) – Automatically disables the primary circuit if the transformer overheats. Once cooled, power is safely restored without user intervention.

Thoughtfully Designed for the Music Lover

PrimaLuna amplifiers are full of small, meaningful touches that make ownership a pleasure. For example, an aluminum screw on the AC inlet discreetly marks the live side for proper orientation. Not flashy — just smart.
