Zesto Audio Andros PS1

For true audiophiles, nothing equals the warmth, dynamic range and fidelity of vinyl records. A critical component of every music lovers Vinyl playback system is the Phonostage or Phono preamp.

When a vinyl record is made the volume of the bass is reduced and the treble is increased. Otherwise, the bass would cut a groove too big for a stylist to read or for the music to fit the record. The phonostage reverses the process by taking the delicate signal from your cartridge and adjusting it so that the bass and treble are restored to their original volume. This common standard is known as the RIAA curve.

Inspired by RCA's vacuum tube circuit designs from the 1930s, the Andros PS1 has been engineered to bring you the clarity and depth of the original recording. Your highs will be crisp but not overly emphasized, your midranges clear and present without being shrill and your lows full and firm without being boomy.

As we went through testing our panel of audiophiles marveled at hearing subtle nuances, discovering new things in recordings they'd played many, many times. They appreciated its clear stereo image with maximum channel separation and minimal phase distortion.

Words are inadequate to the task of explaining the Andros PS1. You simply must hear it to believe it. That's why we're offering a 30-day, money-back guarantee. If you are not satisfied, we will return your purchase price in full.
