(NEWS) Announcing the Andros Spirit Phonostage From Zesto Audio

Thousand Oaks, CA, January 29, 2024

Zesto Audio is proud to announce the launch of the new Andros Spirit Phonostage and 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.

Signature Sound

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 lower price point.”

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.”

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.”

Key Features of the new Spirit

  •  Available in 2 versions MM only or MM/MC
  • Standard MM unit is easily upgradeable to MM/MC
  • 100% Analog tube circuitry without any solid-state devices in the signal path, because tubes are inherently more musical.
  • The tube complement is a quad of 12AX7s, which provides sufficient gain with minimal noise.
  • Safety switch to discharge the high voltage for your added safety when changing tubes.
  • Robust, built-in ESP toroidal power supply for better dynamic range and lower noise.
  • The high-quality built-in MC step-up transformers are designed for better phase linearity. This translates to better stereo imaging.
  • Three of the most popular loading positions are 100, 250 & 500 so you can dial in the best match for your cartridge. Easily adjustable MC “Load on the fly” without clicks or pops so you can hear the change.
  • All MC loading is on the secondary of the MC step-up transformer. This allows all the delicate signal from the cartridge to pass through to the main circuits for the most musical detail.
  • Dual mono circuit which creates better stereo separation
  • All switches and knobs are easily accessible, with nothing hidden inside to adjust.
  • Full size 17″ x 12″ elegantly designed 16-gauge steel enclosure for better grounding and to help isolate the electronic “chatter” from nearby equipment.
  • Illuminated tubes for a more sensual musical experience.
  • Each unit is hand built “Made in the USA.”
  • 50-hour factory burn-in on all circuits and vacuum tubes.
