Preamplifiers — PrimaLuna EVO 300-3

The EVO 300-3 is a tube preamplifier from PrimaLuna, part of the brand's EVO line built to complement its EVO-series power amplifiers within a coherent, fully valve-based signal chain. Positioned within PrimaLuna's mid-tier preamplifier range, the EVO 300-3 focuses on a clean, single-ended signal path with a comparatively compact connectivity set well suited to a straightforward two-source system.

Key specs that matter

Five single-ended analogue inputs and two single-ended outputs are provided, covering a practical range of source components without unnecessary complexity. Gain is 9.7dBu, with input sensitivity at 650mV and input impedance held at a substantial 220k ohms, easing compatibility with virtually any connected source regardless of its own output impedance. Output impedance is a low 256 ohms, keeping the preamplifier tolerant of interconnect cable capacitance and downstream amplifier input impedance alike. Signal-to-noise ratio (unweighted) is a respectable 93dB, with total harmonic distortion plus noise held under 0.5%. At 405 x 385 x 205mm and 24kg, the preamplifier shares its chassis footprint with PrimaLuna's EVO power amplifiers, for a visually coherent stack when paired together.

Sound and use context

Expect the smooth, engaging tonal character PrimaLuna's EVO tube circuitry is known for, with the low output impedance and high input impedance combination specifically chosen to preserve signal integrity end to end - an important consideration in an all-tube system where impedance mismatches between components can otherwise soften detail or introduce unwanted colouration.

Pairing

The 220k ohm input impedance and 256 ohm output impedance combination eases matching with almost any source or downstream power amplifier, and the five-input connectivity comfortably covers a source-rich system without needing an external switcher.

Alternatives

PrimaLuna's own EVO 400-3 sits above this model with added balanced XLR connectivity and wider bandwidth for buyers wanting more comprehensive connection options, worth the further investment if this EVO 300-3's single-ended-only design leaves ambitions for a source or amplifier requiring balanced connection. PrimaLuna backs the EVO 300-3 with the same attention to build quality and component selection found throughout the EVO range, reflecting decades of the brand's tube-circuit design experience.
