About the Eros 500 Select
The Zesto Audio Eros 500 Select is a pair of monaural Class A vacuum-tube power amplifiers built in the USA and designed for high-power, high-flexibility operation. Each monoblock uses a sextet of KT150 output tubes and supports multiple tube types and selectable bias modes, allowing output to be tailored for KT88, KT120, KT150, or KT170 tubes. The amplifiers feature balanced XLR and single-ended RCA inputs, 4-ohm and 8-ohm speaker taps, a subwoofer SpeakOn connector, and an XLR ground-lift switch for hum reduction. Zesto states the amps are hand-built, factory burn-in is performed, and the product ships as a pair for $35,000 before shipping, taxes, and customs.
