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.”

T.H.E Show Newport Beach

“Not every electronics manufacturer is taking the plunge to offer an outboard headphone amp however. Remember when a headphone input could be found on virtually every preamp and receiver? Well, Zesto Audio has taken this to heart and added a headphone amp with front panel input to it’s upgraded Leto 1.5  tube preamp ($7500 pictured below). After listening to the MrSpeakers new Ether planar headphones ($1499) with a well regarded tube headphone amp I switched to the Leto using the same WyWires Red series cable. The difference in spaciousness, air and top end transparency was astonishing. The sound was less between the ears and more convincingly on a dimensional stage at eye level.”Read entire review

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.” Read entire review


Zesto’s new Leto line stage
By John Atkinson • Posted: Jun 7, 2012

Zesto was also using TAD CR1 speakers for the debut of their new Leto tubed line preamplifier ($7500, top), which, like the Andros phono stage (bottom), is made in the USA. With a system comprising a Gamut D200 power amp, a Merrill Williams turntable fitted with a Triplanar arm and a Dynavector XX2 Mk.II cartridge, a Lindemann DAC fed data from a PC running J River software, with WyWire cables used throughout, the Ozawa performance of Mahler’s Symphony 1, with the Boston Philharmonic on a typically bright-sounding DG LP, had me sitting for the entire first movement, so low was the noisefloor and so high the dynamic range. AC power was being conditioned by Spiritual Audio’s VX-9 power conditioner.

“If you have a significant investment in vinyl and an analog front end that merits the best of the best phono preamps, you should by all means audition the Zesto Andros. At its price, its performance competes with much more expensive units. In appearance and sexiness, there’s nothing that comes close.” Read entire reviews

Robert H. Levi – Positive-Feedback Online – November 2011

“As a brand-new company whose first product is a made-in-America phono stage, Zesto has introduced a break-out product and brought to market a winner! Their Andros tube phono stage sports tons of flexibility with bold musicality at an unheard of price point for this level of performance. I am shocked by what they have managed to include for the audiophile under $4000! Plus, the Andros is a world beater in quietude, a wonderful attribute for a phono section. I wish more designers paid attention to this when they design phono stages, particularly tube designers.

I think that you will love the sense of reality the Andros delivers; in addition, the flexibility of its controls, all placed externally for a change, are similar to units costing $10,000. Soundstaging is extraordinary, too. The Andros both over-delivers and under-prices the competition. If you need a phono stage, I wouldn’t wait for the price to go up on this beauty. It begs the question, why spend more than the cost of the Zesto Andros PS1? The Andros receives my highest recommendation and top-choice rating for a phono stage anywhere near this price!” Read entire review
