The EVO 100 Tube Power Amplifier is a fully tube-based stereo amplifier designed for high-end two-channel systems built with separates. Focused on musicality, reliability, and long-term performance, it delivers a rich, natural sound with excellent midrange presence, smooth highs, and controlled, articulate bass.
With 40W per channel (EL34) in stereo and the ability to switch to mono mode (~82W), it offers flexibility for different system configurations. PrimaLuna’s engineering emphasizes transformer quality and circuit design over raw power, resulting in a more refined, dynamic, and engaging listening experience.
