About the Eros 300 Mono
The Zesto Audio Eros 300 Mono is a high-end, hand-built, pure Class A push-pull ultra-linear monoblock power amplifier designed for exceptional musicality and power. It utilizes a matched sextet of six KT88 output tubes and two gold pin ECC82 (12AU7) tubes, with auto bias technology eliminating the need for manual adjustments. Key features include transformer-balanced XLR inputs for noise rejection, a ground lift switch for hum elimination without safety risks, choke-based power supply with custom toroidal transformer, and no negative feedback for superior dynamics. Output taps for 4 and 8 ohms ensure compatibility with various speakers, and it runs hot as typical for Class A operation. Reviewers praise its rich tonal palette, three-dimensional soundstaging, powerful bass grip, and reliability. Updates are available from the manufacturer. It remains in production with ongoing support.
