EVO 300 Tube Preamplifier

The EVO 300 Tube Preamplifier is a high-end all-tube control center designed for serious two-channel systems built with separates. Featuring a true dual-mono architecture and tube rectification, it delivers exceptional imaging, low noise, and a rich, natural sound with outstanding depth and realism.

Positioned above the EVO 200, it incorporates upgraded internal components and premium materials, including Swiss-made wiring and refined circuitry, resulting in greater transparency, wider soundstage, and improved tonal accuracy. Its low-gain design and advanced power supply ensure an ultra-quiet background and highly detailed musical presentation.

Key Features

• All-tube preamplifier (pure analog design) for maximum musicality and signal integrity
• Dual-mono topology (two independent preamps in one chassis) for superior imaging and separation
• Tube rectification (2 x 5AR4) lowering noise and enhancing tonal richness
• 6 x 12AU7 tubes in gain and driver stages for depth and harmonic detail
• Point-to-point hand wiring (Swiss-made OCC copper) for maximum signal purity
• ALPS Blue Velvet analog volume control for precise, noise-free operation
• SuperQuiet relay-based input switching minimizing interference and crosstalk
• SmartGain design (~10 dB) reducing hiss and improving system matching
• PerfectMatch impedance optimization for ideal source compatibility
• Dual toroidal transformers + AC Offset Killer for ultra-low noise floor
• Home Theater Bypass + multiple RCA inputs/outputs for flexible integration
• No DAC / no phono stage to preserve purity and long-term upgradeability
