Testimonials


2015 Editors Choice Award  - The Absolute Sound

"No analog devotee will not enjoy listening to the Zesto Andros Phono Preamplifier. It had an addictive sound that combined the 12AX7 tube's well known golden glow warmth with uncommon extension at the extremes of the audioband... I highly recommend the Zesto Andros. It's among the more enjoyable and satisfying phono preamplifiers I've auditioned at any price"
- Michael Fremer, Stereophile, March 2013

"The new Zesto Andros Phono Preamplifier clobbers the original, and may just be the best piece of audio gear designed by George Counnas to date. Combine trend setting flexibility, head turning design, glorious performance, and super competitive pricing and you will understand the impact of this beauty in my reference system. If you are searching for a top performing phono stage, consider the Andros 1.2. It will open a window to the glories of high-end, high-definition sound without your having to take on a second mortgage. My highest recommendation!"
 - Robert H. Levi, Positive Feedback, April, 2015 (read the review)

Robert Harley in 2012 CES show report stated the Zesto room (at 2012 T.H.E. Show at The Flamingo) exhibited "a rare epiphany in which the system so totally disappears that the music seems to just exist independently of the hardware. The system, put together by Zesto, Lindemann, and retailer Audio Revelation, was absolutely jaw-dropping in its presence and realism." Robert also awarded this room one of his "Best Sound" awards.

"In a nutshell, the Andros is like finding the Mona Lisa at a yard sale. It is the best bargain in a high-end phono stage I have discovered since I have been reviewing. Buy it, max out the ancillaries, and move on!"
 - Robert Levi, Positive Feedback Online, Nov-Dec. 2011 (read the review) 

Overview


Zesto Andros Phono Preamplifier
The Andros Phonostage has won numerous award including Stereophile's 2013 "Analog Product of the Year" finalist as well as their Class A Recommended Component. In 2013 the Andros received The Absolute Sound's "Golden Ear" award and for 3 years in a row received their "Editor's Choice Awards".

Inspired by RCA’s vacuum tube circuit designs from the 1930s, the Andros 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.


A Startling Difference

As Zesto went through testing, a 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.

Zesto's Story, as told by George Counnas, President of Zesto Audio


Fussy Can Be Good

I’ve loved music all my life – as a musician, record producer and audio engineer. That makes me fussy about sound. That’s a good thing.

If you want something done right…

Digital technology has its place, but true audiophiles know that for the truest, purest sound, nothing beats analog. As I returned “home” to the warm, wonderful world of vinyl, I looked for the gear that would deliver the highest fidelity. I wasn’t satisfied.

Vacuum tubes: everything old becomes new again

As a young man in England, I designed vacuum tube circuits. I worked for DECCA Navigator -- at the time Britain’s largest electronics company -- as part of a research and development team designing airborne navigational systems for the Royal Air Force.

Vacuum tubes faithfully convert the delicate signal from my turntable and bring warmth and harmonic tonality like nothing else can.

My quest for perfection

I started doing research on past phonostage designs going back to the original RCA circuits of the 1930’s. These guys got a lot of things right, even though their tools were slide rules and trial and error.
Their “classic” designs were my starting point.

But I had the advantage of CAD software to simulate electronic circuits. Ah yes, the old and the new. But even with the engineering skill, history, technologies, in the end it’s designed by how it sounds, by ear.

Voila! Here’s my baby!

One year later, after 71 circuit revisions with hundreds of component upgrades, I have a phonostage that I am proud to put my name on. It gives me joy to listen to music.

The Andros PS1 Phonostage is my baby. I compromised on nothing.

The resisters are very quiet, the capacitors are transparent, and the transformers have minimal distortion. To make sure its visual aesthetics lived up to its sound, I had an industrial designer and an artist collaborate to create an elegant enclosure that’s built like a tank.

In the end, however, the Andros PS1 is about what you hear. Hearing is believing.
