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.
So I built my own.

Vacuum tubes: everything old becomes new again
Vacuum tubes faithfully bring warmth and harmonic tonality like nothing else can.



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.

So I have many years of experience designing, creating and bringing to market high-end electronic equipment. The difference here is that no one’s life is at stake.

My quest for perfection
I started doing research on past tube designs going back to the original RCA circuits of the 1930’s. Those 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.

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 (Musky Mistry) and an artist (Carolyn Counnas) collaborate to create an elegant enclosure that’s built like a tank.

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

Munich 2016:
Best Sound (For the Money) by Neil Gader,
 The Absolute Sound, May 20th 2016
“Camped out at HiFi Deluxe was a superb display of musicality courtesy of the Zesto Audio
 Leto preamp ($7500) and Bia 120 stereo amp ($12,500) and Joseph Audio’s Profile ($7000) loudspeaker. The small Euro-scale system could lay back but shift gears on a dime and was an exemplar of natural tonal color and dynamic composure.”

Leto Premap - Positive-Feedback Online - September 2012

"New from Zesto Audio comes the tubed Leto Preamp, pushing the envelope in value and performance in its price range and beyond. With styling similar to the Andros Phono stage, the Leto is a powerful sounding, highly detailed, fantastically quiet, and superbly musical masterpiece that will complement the finest systems. Designed by a brilliant and pragmatic designer who knows great sound and ergonomics, the Leto performed like a thoroughbred in every way musical, and was a joy to control and adjust. The fun factor while working with the Leto made me rethink what has been missing in minimalist preamps that cost even more money these days. What a jewel! The Zesto Audio Leto is a killer design to my way of listening and loving recordings, and may just be the preamp you will buy and keep for the very, very long haul. The Leto receives my highest recommendation." Read entire review

Leto Line Stage Preamplifier - Audiophilia - September 14th 2012

"I have spent many hours listening to the Leto and Andros combination at Wes Bender’s NYC/Studio. I have also listened to the Leto with the EAR 324 phono stage. The sound of the Leto is on the warm side of the spectrum but not so much as to be in any way objectionable. To be clear, this is not an ‘old school’ tube sounding amplifier. From top to bottom, the sound is very well balanced. It has enough resolving power to allow vocal and instrumental textures to be clearly heard. The Fairfield Four’s Isaac Freeman’s bass vocals are presented with their full richness, bloom and textures intact. I have heard this group’s vocals on other line stages that glossed over these details resulting in a bland presentation. Not so with the Leto". Read entire review

Andros Phonostage PS1 - TONEAudio - September 2012

"After a solid month of intense audition, the Zesto Andros PS1 exhibits no weaknesses whatsoever. While it has a beautiful visual aesthetic, it continues to be a joy to listen to and is ultimately musical. With many audiophiles on a quest for gear that is increasingly more resolving, it might be easy to overlook the Andros PS1, but truly wise LP lovers will treasure the Zesto because the balance is just right. Much like a car with perfect 50/50 weight balance, along with equal amounts of stop and go, the Andros PS1 doesn't maximize any one parameter at the sake of another and that is its magic."

Zesto Audio Andros PS1 phono stage, Merrill Williams REAL 101 turntable, Tri-Planar tonearm, Lindemann DAC, TAD CR1 loudspeakers and stands, Zesto Audio Leto preamp, all cabling by WyWires. Loved this room... easy, effortless, and musical. The TAD speakers are great, but then the rest of the system has to be up to snuff as well. Kudos to the people here! Read entire review

RMAF12: Bringing it with Zesto Audio, TAD and WyWires

Posted on October 25, 2012

"So, yes — Zesto is certainly one brand that gets it right — to me, at least. Much like their sweet demo at Newport, the sound here at RMAF was lovely: liquid, holographic, dynamic and detailed. This is, in my not-so-humble-opinion, a finisher system. Done, off the merry-go-round, go start investing in estate sales of giant record collections. If you have a huge room, you might want to go elsewhere, but for “normal” rooms, ska-doosh". Read entire review

"Its sound is unbelievably smooth and velvety; harmonically rich, full, and vividly textured; marvelously rounded, tactile, and dimensional, with great body and solidity; and completely natural in its musicality and freedom from any of the usual sonic hype, audiophile style." Read entire reviews

Reviewed by Ray Seda - Dagogo - March 2012

"The sweetness and delicate nature of the Zesto Andros PS1’s delivery in the midrange and highs are almost counter-intuitive to its ability to also very competently amplify and deliver the sheer, explosive low frequency energy and dynamics that the record playback system sends to it."
