PrimaLuna EVO 100 Tube Power Amplifier

The PrimaLuna EVO 100 Power Amplifier represents the pinnacle of accessible valve amplification, offering audiophile-grade performance without the complexity traditionally associated with tube technology.

Exceptional Craftsmanship

Each PrimaLuna EVO 100 features meticulous handmade construction with a heavy-gauge, fully vented steel chassis finished with five coats, each hand-rubbed and polished. Inside, you'll find point-to-point wiring using only the finest Swiss silver wires—a level of detail typically reserved for far more expensive valve equipment.

Premium Components

This power amplifier incorporates custom-designed toroidal and EI-frame transformers, manufactured to exacting specifications from one of America's most prestigious transformer designers. Each transformer is fully encapsulated to ensure minimal hum and optimal isolation, delivering the renowned PrimaLuna sound signature that combines valve midrange magic with sparkling highs and deep, solid bass.

Additional premium components include:

• Nichicon and DuRoch polypropylene capacitors
• Superfast Philips rectifier diodes
• Ceramic tube sockets
• Gold-plated heavy-duty WBT-style speaker terminals with solid shaft construction
• Gold-plated panel-mounted RCA and XLR input/output jacks

Exclusive Technology

The EVO 100 features PrimaLuna's proprietary Adaptive Auto Bias™ circuit which monitors and smoothly adjusts tube bias continuously, dramatically reducing distortion while eliminating the need for manual bias adjustments. This exclusive technology makes tube amplification truly user-friendly without compromising sonic performance.

Versatile Operation

A distinctive feature of the EVO 100 Power Amplifier is its stereo/mono switch, allowing for flexible system configuration. In mono mode, the amplifier delivers a substantial 82/84 watts (depending on tube type), making it ideal for powering more demanding loudspeakers when used in pairs.
