Welcome to our PrimaLuna EVO 300 Tube Preamplifier Review, where we take you on an audiophile-grade exploration of this masterclass in analogue sound. With features like PrimaLuna’s exclusive AC Offset Killer and a dual-mono architecture, the EVO 300 is engineered to deliver an expansive soundscape that reveals unprecedented layers of musical detail. Whether you’re chasing the purest acoustic textures or a naturally vibrant performance, this preamp stakes its claim as a new benchmark in high-end audio.

Design & Build: Precision Wiring Meets Timeless Elegance

Every aspect of the EVO 300 speaks to meticulous craftsmanship. Its chassis is both robust and refined, housing hand-wired, point-to-point signal paths that use high-grade Takman resistors to ensure linearity and ultra-low noise. Complementing this is the coveted Japanese Alps Blue Velvet potentiometer, delivering silky-smooth volume control and precise channel balance.

Pure Audio Performance: Silence You Can Hear

The magic of the EVO 300 lies in its ability to produce a startlingly quiet backdrop. PrimaLuna’s AC Offset Killer neutralises transformer noise and DC offset to depths most designs only aspire to, revealing a sense of space that brings each note into sharp relief. Add dual toroidal power transformers—each potted in non-microphonic resin—and tube rectification, and you have a preamplifier that offers an honest, uncoloured representation of your favourite recordings.

Technical Highlights: What’s Under the Hood?

• Dual Toroidal Power Transformers: Emit just a tenth of the magnetic field of ordinary transformers, ensuring exceptional 3D imaging and soundstage depth.
• Tube Rectification: Three 12AU7 tubes per channel in a Dialogue Front-End Circuitry configuration, delivering increased bandwidth and sub-0.5% THD for natural, lively tones.
• PerfectMatch Impedance: Provides a steadfast 100 kΩ load to source components, optimising signal transfer and system synergy.
• SmartGain Design: At a modest 9.7 dB gain, the EVO 300 keeps noise floor negligible, preserving tube dynamics and warmth.
• SuperQuiet Line Inputs: Sealed relay switching eliminates contact chatter and signal leakage, ensuring clarity at every source change.

Who Should Consider the EVO 300?

If you’re an audiophile seeking a preamplifier that elevates every genre of music—from delicate solo piano to orchestral masterpieces—the EVO 300 is designed for you. It’s also ideal for those with high-quality source components (DACs, phono stages, CD transports) looking to unlock the next tier of detail. Paired with a neutral or slightly warm power amp, the EVO 300’s sonic signature truly shines.
