EVO 100 Preamplifier

The EVO 100 Tube Preamplifier is a fully tube-based control center designed for high-end two-channel systems built with separates. Engineered with a dual-mono topology and tube rectification, it delivers a rich, natural sound with exceptional depth, low noise, and precise imaging—bringing out the full character of any connected source.

Focused on signal purity and long-term performance, it features handcrafted point-to-point wiring, premium components, and a minimalist gain structure to reduce noise and preserve musical detail. The result is a highly transparent yet musical presentation, ideal for pairing with dedicated power amplifiers.

Key Features
