Zesto Audio Eros 300

The Auto Bias system automatically adjusts the voltage for the KT-88 tubes, ensuring they operate at optimal levels without requiring manual calibration. This simplifies maintenance and guarantees consistent sonic performance over the life of the tubes.

Yes, the Eros 300 features both XLR and RCA inputs. The XLR input is transformer-balanced for superior noise rejection, while the RCA input provides a standard 100K Ohm impedance for compatibility with most single-ended preamps.

By eliminating negative feedback, the amplifier avoids the phase shifts and timing errors often associated with feedback loops. This results in a more open, dynamic sound with improved transient response and a more natural musical presentation.

The Eros 300 includes an XLR ground lift switch specifically designed to eliminate ground loops and hum. This provides a clean signal path, especially when integrating the amplifiers into complex high-end audio systems.

These taps allow you to optimize the power transfer between the amplifier and your specific speakers. By matching the tap to your speaker's nominal impedance, you ensure the amplifier delivers its full 150 watts of power efficiently and maintains tight control over the drivers.

The six KT-88 tubes per channel provide a signature blend of rich, life-like warmth and significant power. You get the classic harmonic texture associated with tube amplification, paired with the authority and detail required for modern, high-resolution speakers.
