State of the Art Tube Designs for Music Lovers!

One of the Few

Zesto Audio is proud to be one of the only manufacturers to offer a 100% all-tube analog phonostage at this price point. You will receive the same quality and sonic excellence that you would expect from any Zesto product, hence the name Andros Spirit.

Design Philosophy

Zesto Audio has a long history of producing award-winning Phonostages since the company launched the original Andros PS1 Phonostage in 2010. George Counnas, Founder, and Chief Design Engineer of Zesto Audio says, “I designed the Spirit so it would retain only the essential features of its predecessors, while still offering the Zesto Audio signature sound.” George admits how challenging it is to design a high-quality product that sounds good at a low price point.

Unique Safety Feature

The Spirit has a unique component called a safety switch. George says, “I was inspired by the old Telefunken Radios back in the 50s and 60s that used a safety switch to discharge the high voltage. I included this feature for your added safety when changing tubes.”

 New line – New Enclosure Design

The new full-size 17″ x 12″ enclosure design represents the new Spirit line of products in development at Zesto Audio. The Spirit is made with 16-gauge steel for better grounding to help isolate the electronic “chatter” from nearby equipment. Carolyn Counnas, VP, and Industrial Designer for Zesto Audio says, “I wanted our customers to feel they had been personally invited into the inner sanctum of tube electronics, solder joints and all. I get mesmerized by the LED illuminated tubes which bring an added sensual experience to your listening pleasure.”

Robust Power Supply

(Energy Source Power Supply) We named it the ESP Supply because it anticipates the energy needs of the music. Zesto’s ESP Supply unlocks the true potential of the circuit, so it is at ease and doesn’t have to work as hard. It allows more music to flow through with more detail. It also creates a more dynamic presentation, the quiet passages are quieter, and louder passages have more punch.

 Why Andros?

Andros is a Greek island and the home of George’s grandmother’s family. Andros is the name of the Zesto phonostage family.
