PrimaLuna EVO 200 Tube Integrated Amplifier

All-Tube, Output Transformer-Coupled Headphone Amplifier

PrimaLuna uses its main tube amplification circuit rather than a conventional solid-state op-amp to power headphones. A voltage-divider network provides the appropriate output for models ranging from Sennheiser dynamic headphones to power-hungry Audeze and HiFiMAN planar designs.

SuperQuiet Line Inputs

Premium sealed relays are positioned close to the rear-panel inputs to keep the signal path exceptionally short. Only the selected input relay closes, while the others remain isolated to prevent unwanted signals and noise from entering the audio path.

Custom Toroidal Power Transformer

PrimaLuna uses a massive, custom-made toroidal power transformer to minimise magnetic interference, vibration and acoustic noise. Its metal enclosure and non-microphonic resin further reduce noise while protecting the windings from moisture and long-term deterioration.

Custom Wide-Bandwidth Output Transformers

PrimaLuna’s output transformers are custom-designed and wound in-house to deliver extended bass, open high frequencies and powerful, controlled sound. Their wide bandwidth allows the amplifier to prioritise musical performance while operating its tubes conservatively.

Adaptive AutoBias

Adaptive AutoBias continuously monitors the output tubes and makes seamless adjustments in real time. The passive circuit sits outside the signal path, reduces distortion at higher listening levels and helps extend tube life with minimal maintenance.

Extensive Tube Compatibility

A fine-tuning switch optimises operation for EL34- and KT88-family tubes. Compatible options include 6L6G, 6L6GC, 7581A, EL34, EL37, 6550, KT66, KT77, KT88, KT90, KT120 and KT150, allowing you to tailor the amplifier’s character to your system and preferences.

Point-to-Point Wiring

The complete signal path, including its resistors and capacitors, is meticulously hand-wired by skilled craftspeople using heavy-gauge cable. This construction provides direct, durable connections without relying on thin circuit-board traces.

No Internal DAC or Phono Stage

Keeping rapidly changing digital technology and specialised phono circuitry outside the amplifier allows you to select components that suit your sources, cartridge and budget. This modular approach also helps the amplifier remain relevant for years to come.

Bad Tube Indicator

If a tube fails, Adaptive AutoBias immediately places the amplifier into protection mode to help prevent damage. A red LED identifies the tube requiring replacement, making maintenance quick and straightforward.

SmartWatts for Extended Tube Life

PrimaLuna operates its output tubes at approximately 417 volts across the plates and screens, using the minimum practical dissipation without introducing crossover distortion. This reduces tube stress, supports longer operating life and maintains excellent sound quality.

Performance Beyond the Power Rating

Power output alone does not determine sound quality, bass impact or musical engagement. PrimaLuna prioritises transformer bandwidth, circuit quality and controlled tube operation to deliver dynamic, authoritative performance at everyday listening levels.

Tailor the Sound to Your System

Different output tubes allow you to fine-tune the amplifier’s tonal character to complement your loudspeakers, room and personal preferences. This broad compatibility provides flexibility for future system changes and encourages experimentation with different tube types.
