About the Andros
The Zesto Audio Andros Spirit Phonostage is an affordable, hand-made in the US, fully tube-based phono preamplifier designed to deliver the signature Zesto sound with essential features. It uses four JJ ECC83S/12AX7 tubes, 100% analog tube circuitry without solid-state devices in the signal path, and features an ESP power supply. Available in MM-only or upgradeable MM/MC versions, it provides high gain with minimal noise, housed in a 16-gauge steel enclosure for improved grounding and isolation. Praised for its musicality and value, it continues Zesto's legacy of award-winning phonostages since the original Andros PS1 in 2010.
