Zesto Audio Eros 300

By removing negative feedback, the Eros 300 preserves the natural transient response and punch of the music. This approach allows the amplifier to sound more open and dynamic, avoiding the compressed, sterile quality often found in designs that rely heavily on feedback loops.

Not at all. The Eros 300 features auto-bias technology, which automatically manages tube current and ensures consistent performance. You won't need to manually adjust or monitor the bias as the tubes age, making the maintenance experience essentially hands-off.

Yes. With 150 watts of pure Class A power and a robust, choke-based power supply, these monoblocks are designed to drive demanding, low-efficiency speakers with ease. They provide the necessary current and headroom to maintain control and clarity even at higher volumes.

The choke-based power supply acts as an energy reservoir, ensuring the amplifier can deliver power instantly when the music demands it. This results in a sound that feels effortless and dynamic, preventing the compression that can occur during complex musical passages.

Yes, the Eros 300 is versatile in its connectivity. It includes both XLR and RCA inputs, with the XLR input being transformer-balanced to provide excellent noise rejection, which is particularly useful if you have long cable runs.

Each unit measures 17 inches wide, 20 inches deep, and 10 inches high, and weighs 64 pounds. Because they are Class A amplifiers, they will generate heat, so ensure you have adequate ventilation space around the enclosure to allow for proper airflow.
